The trunk does not stay on the VAZ 2115 - what are the reasons, how to change it

Adjusting the tailgate lock.

1. We unscrew the lock lock so that it can be moved with light force.
2. Now you need to close the door and look through the glass to ensure that the lock spike is opposite the latch socket.
3. After this, we move the latch all the way back and slam the door. This will ensure the lock lock is in the optimal position.
4. Open the door and tighten the bolts securing the clamp in the position in which it was installed.
5. It is also necessary to check that the door closes. If the door does not close tightly. then you need to remove the adjusting plate from under the clamp.
6. If the door closes too tightly, on the contrary, you need to add a plate under the latch.

Replacement options

The first option is banal to the point of impossibility - buy a similar lock.
Moreover, you will need to buy the entire lock, and not a separate part, because the design of the mechanism is non-separable. Replacement is carried out when the old lock is completely dismantled. This solution should be considered temporary, since the production technology is the same and the problems will remain. Over time, a new lock will have to be replaced. The only positive side of this solution is that it is quite cheap. The second option involves completely replacing the mechanical lock with an electrically controlled drive. What does this give?

1. Secure trunk closure.
2. Possibility to control the position of the rear door from the driver's seat.

Installing such a system is not the cheapest pleasure, but the final result will really please the user. The electronic drive is much more convenient to use and is a reliable replacement for its mechanical counterpart.

Dismantling the old castle

The VAZ 2114 model will be taken as an example.

The following tools will be useful in your work:

• set of Phillips screwdrivers;
• key to 8.

The replacement sequence is as follows:

1. First of all, in order not to damage the interior lining of the trunk, we remove ten plastic fasteners, and then the plastic casing from the lock.
2. We remove the casing, then unscrew the nut that secures the lock in place.
3. Unscrew the wires that are in the way.
4. Next, you need to unscrew the right fastening nut and remove the inner part of the lock from the fastenings.
5. You can inspect the integrity of the spring and core. If these parts are defective, then the problem is in the mechanism. In any case, everything will have to be changed.

If you prefer the economical option of replacing it with a new mechanical lock, then install it in the reverse order as described.

Drive installation

Adjusting the position of the trunk lid is possible if, instead of a mechanical lock, you install an electronic device, in this case a drive. To install it you will need:

• universal drive installation kit for the machine;
• metal cable with a cross-section of 1.5 mm and 500 mm long;
• two contact connection wires of 4.5 m each;
• screws with wide heads;
• opening button for the lock;
• retainer;
• fuse;

We install the drive in the prepared place, according to the instructions. Next, you will have to make several amendments to the design:

The VAZ trunk is opened by pressing a button that can be installed in the cabin.

The electronic device is adjusted according to the included instructions. All other nuances that should be taken into account when installing the device in VAZ models have been indicated.

Which system is better?

To sum up, which engineering solution is better for opening, closing and fixing the lid or tailgate is difficult to answer unequivocally. Each of them has its own advantages and disadvantages. This may be a biased opinion, but gas shock absorbers undoubtedly performed the best. The mere fact that the old units, having served their time on Nivas produced in the 70s and 80s and being transferred to cars of later releases, continue to successfully perform their functions, gives a chance to think.

Use of reliable gas shock absorbers

Is it worth it to rush to use new technologies if the old ones are more reliable? However, as follows from the description above about Renault Logan, there are exceptions to the rules. In the meantime, engineers are looking for new ways to solve technical problems, numerous “Kulibins” are applying them in practice through trial and error, experimenting with components and assemblies of their cars, creating homemade test benches from them.

Torsion bars, yes, the standard rubber wears out over time.

The castle has its own ambush. It is attached to the lid in such a way that two thin layers of metal are pressed together with a void between them. Over time, all this equipment becomes loose (the metal bends). Even if a lift helps, it doesn't last long.

Shvi on the lid will reduce noise. adjustment and pulling will remove the noise. but how, what and how much to answer to whom - I will decide myself, without outside prompts. Am I making myself clear?

Preventing door jams

The main reason for the breakdown: long-term operation, but the service life of the part is reduced if the driver does not carry out preventive maintenance. Basic moments:

1. Cleaning of internal parts, treatment with special substances.
2. Power loop lubrication.
3. Removing adhered dirt. The procedure is carried out at least twice a year: in spring and autumn. Active ingredients for treatment: Liqui Moly Schnell-Reiniger cleaner, Liqui Moly Wartungs-Spray weiss dirt-repellent white lubricant.
4. Lubrication of hinges, internal parts, rubber seals, door stops.

The procedure is especially relevant before the winter season, when the treatment prevents the mechanism from freezing when moisture enters. Spring prevention minimizes damage to the door mechanism from ultraviolet radiation.

Door opening method

If the VAZ-2109 door does not open from any side, then the cause of the breakdown is difficult to determine, since there is absolutely no access to the lock mechanism.

A somewhat simplified version of the breakdown occurs when the door does not slam shut completely and gets stuck in that position. Then it is possible to reach the latch from the outside with a sharp object.

To open a jammed door, you must first perform the following steps:

When simple means do not produce results, the door will have to be opened from inside the cabin, which will require removing its trim.

In practice, this is not easy to do, because the casing is pressed by the sash and it is difficult to pull it out without damage. But there is still no other way out: it is better to damage the inner panel than to mutilate the door itself.

To dismantle the decorative panel, you need to unscrew the armrest handle with a screwdriver, and then the storage shelf located at the bottom of the door card. Then the button that secures the lock from above is unscrewed and removed.

Lastly, the window lifter handle and the opening handle frame are removed. Now you need to carefully separate the lining from the body using a pair of flathead screwdrivers and another suitable tool.

You may be able to remove the trim without visible damage.

When the decorative panel is removed, access to the lock mechanism from the inside opens, although getting to it is inconvenient. Immediately check whether the rod running from the handle to the lock has fallen off. This is a fairly common malfunction that can be fixed with little effort. Put the rod in place and open the door.

If there are no visible reasons for the breakdown, simply try to open the door from the inside by working on the mechanism with various tools. If necessary, enlist the services of an assistant who will press or pull the door from the outside. Experience shows that such procedures for opening jammed doors can take a lot of time, so you will have to be patient.

Causes of malfunctions

There are several types of malfunctions that prevent the doors of a VAZ-2109 from opening from the outside or from both sides:

The latter malfunction sometimes occurs due to the fault of the car owner himself, who has decided to change or repair the door lock. Having put it in place and not fully tightened the screws, the owner of the VAZ-2109 accidentally slams the door, after which it will not be possible to open it with the handle.

Troubleshooting

If a key or silumin rod breaks, you should not immediately buy a new block with a handle. On sale you can find special repair kits for VAZ 2108-099 door handles, which contain these parts in 2 copies.

This way you will save money and easily change the key yourself by removing the handle using the following sequence of actions:

1. Remove the decorative panel.
2. Disconnect the rod connecting it to the locking device from the handle mechanism.
3. With the glass fully up, unscrew the 2 fastenings of the handle to the door card.
4. Remove the handle, replace the parts and put it back.

If the rod is disconnected, then you need to remove the inner lining and put it in place, as described above. Using the moment when the facing panel is removed, check what caused the disconnection of this rod so that history does not repeat itself when the door is slammed.

Malfunctions of the locking mechanism can only be eliminated by removing it. In a situation where the device has a lot of wear, as happens on the driver and front passenger doors, it is recommended to replace the lock with a new one.

After installing it in place, adjustment will be required to ensure precise alignment of the locking parts. To adjust, the lock will have to be fixed in different positions, achieving the optimal one.

Features of the trunk lid of the Chevrolet Niva

In general, “features” is too strong a word. The lid is just like a lid, and its only “unusuality” is that it opens not like the old Niva (lifting up), but, at the whim of the engineers, to the left. And I must say, this is quite an interesting solution! An example, apparently, was the “English” Land Rover Defender, produced for safari travel. This comparison especially suggests itself after you see the spare wheel, which is held on by the lid (or, more correctly, the door) of the trunk.

Apparently, the Americans, who helped Russian developers implement the project to create a joint crossover, tried to take into account all the nuances of Russian roads, and therefore quite a lot of attention was paid to the strength and reliability of the car. Right down to the design of doors. The trunk lid here is devoid of any devices such as torsion bars, springs and shock absorbers. And this is probably its value. At least, car enthusiasts do not have to become inventors and look for solutions to the problem, simultaneously racking their brains about where to drill a hole or weld a piece of iron. In addition to the fact that the lid opens to the side, it only requires hinges.

Chevrolet Niva trunk lid

By the way, it has become more convenient to fix it - there are three positions. Quite remarkable. After all, there is no need to open it all the way if you need to take and put some small thing.

Are there any complaints about the luggage compartment door from car enthusiasts who have chosen to purchase this “iron horse”? Well, what would we do without them! Considering that the lock of the luggage compartment lid (door) is electrically driven, corresponding malfunctions also occur here. They especially often complain that the wiring is frayed. The fact is that they are a bit harsh, and fractures occur in places close to the door hinges. This can be eliminated, in general, quickly, but it is still unpleasant. You have to disassemble the connectors to find the breakdown. Many owners “sin” on the fuse box, and therefore, unable to find the true reason why the lock does not work, they spoil their nerves and mood.

The device of the tailgate

The following malfunctions that could occur in the trunk lid are related to the wiper and glass washer. However, judging by the reviews of the owners, these devices do not cause any problems. Difficulties may also arise when changing the rear door itself, when it is necessary not only to correctly connect the wires for the devices, but also to make adjustments, adjust the tightness of the seals, adjust the lock latch, adjust the location of the hinges and carry out a lot of other manipulations.

Another “little thing” that can ruin a car owner’s mood is the creaking of the hinges when driving. In principle, you can ignore it, but understand for yourself how painfully any malfunction, even a tiny one, hurts! Our “Kulibins” have been looking for a solution to this problem for a long time, but, as often happens, it lay on the surface. It turned out that you just need to lubricate the hinges with any grease - and that’s it! The squeaks instantly disappear.

How to replace the trunk lock on a VAZ 2113-VAZ 2115?

1) As for hatchbacks, their lock can be easily removed, and there won’t be any problems with sedans either, but the principle of replacement on two different bodies is different, first we’ll talk about hatchbacks, if you have a specific car with such a body, then on theirs first remove the upholstery that is attached to the inside of the trunk lid with 10 pistons, it is not at all difficult to remove, all the pistons were pry off with a screwdriver and after that the upholstery was put aside, for more details on how to do this, read the article: “Replacing a spoiler on cars”, point 1 Study the nd in that article carefully.

2) After the upholstery is removed, unscrew two bolts and thereby remove the lock from the car, but only when unscrewing the bolts, take into account the fact that under one of them there are several terminals, one of which goes to the tailgate wiper motor, and the other to the stop -signal, and that’s it, the lock has been removed from the car.

Note! To adjust the lock on this type of car, take a spanner wrench (You can use a spanner if you don’t have a spanner, it’s just possible to break off the bolts securing the lock) and use it to loosen the bolts holding the lock (Do not turn them out completely, in this case, by the way, you are adjusting the position of the lock, due to in a knocked down position, the trunk lid may be difficult to lock, lock with a blow, or it is very poorly fastened and opens at all on bumps), then move the latch in the appropriate direction, ensuring that the lock, when closing the trunk lid, enters the latch without strong force and that the trunk is firmly locked (see photo 1), if you need to adjust the trunk lid in height (In other words, the lid does not lock well and it has free movement if you pull the lid), then in this case completely unscrew the bolts securing the latch, remove it and then then select the adjustment plates behind it (Always remember one thing, the more plates you put, the higher the trunk lid will stand and it will have free movement, the fewer plates there are, the worse the trunk lid is locked and the tighter it is pressed against the body car, and if there are no records at all, then you won’t be able to simply close the lid, so you look for a middle ground, see photo 2)!

3) As for sedans, first remove the plastic clips using a screwdriver, which strengthen the lock cover, and then the cover is removed (see photo 1), and when it is removed, proceed to disconnect the rod, for this the end of the rod (the rod is indicated in blue with the arrow in photo 2) remove it from the hole indicated by the green arrow, but keep in mind that the tip is bent and secured with the screw indicated by the yellow arrow, so first unscrew the screw, then straighten the bent end of the rod with pliers and only then pull the rod out of the hole in which it is located Once this is all done, remove the rod from the hole in the lock cylinder lever (see photo 3) and remove it, immediately after which unscrew the three nuts that strengthen the lock (see photo 4) to the trunk lid and remove it from the studs and Finally, unscrew the bolt that secures the lock

(see photo 5) and remove it (see photo 6).

Note! The new lock is installed in its place in the reverse order of removal; when installing the nuts, do not tighten them all the way at first, but rather tighten them a little and try closing the trunk lid in different positions of the lock, then you will adjust the lock to the lid and it will lock normally!

Where to begin?

Initially, tuning the trunk 2115 begins with the selection of design. At this stage, it is necessary to measure and think about everything in detail, for example, where the amplifier, subwoofer, lighting will be placed, whether it is worth making a raised floor, etc. After this, you need to decide on the places where the structure will be fixed. Upon completion of the design and calculations, you can proceed directly to the manufacture of the structure itself.

The construction of the structure begins with cardboard. That is, cardboard is great for making templates. However, it is recommended to make templates from thick, single-layer cardboard; if this is not available, then you can use whatman paper (whatman paper will have to be glued to a sheet of plywood). This will significantly reduce the number of errors.

After the templates are made, they need to be transferred to a sheet of plywood. Then you need to cut out the parts from the plywood. Cutting must be done using a jigsaw. This is due to the fact that using a jigsaw speeds up the work and also ensures an even cut.

After all the parts have been made from plywood, it is recommended to trim the edges. But individual elements can also be treated with drying oil. This will prevent deformation of the plywood and increase its service life.

How to open a VAZ 2109 without a key

Method 1

This method is the simplest and most harmless. A prerequisite for its use is the presence of factory door lock buttons in the cabin, or any other ones in the form of a fungus. They look like this:

If you have such buttons, then you are very lucky. Now you need to find a thin rope about 1 meter long, maybe smaller, the main thing is that it reaches from the roof of the car to the door lock lock button and still has about 30cm left. Thin laces from your running shoes may work. We definitely don't need flat laces. Now that we have a rope of the required length, we make a tightening loop at one of its ends, with a diameter approximately twice the size of the door latch cap.

The most important and difficult moment comes. We press the driver's door of the car from above, in the place indicated in the picture.

We lower the prepared rope and, after some attempt, depending on your accuracy, put it on the lock lock. Next, we lower the rope along the doorway so that it becomes parallel to the roof and tighten the loop on the latch. Now all that remains is to pull out the lock latch and your VAZ 2109 will be opened without a key and without damage.

Method 2

There is another way to open a VAZ 2109. In this case, you can also avoid damage if you do everything carefully. If your door lock latches are not in the form of a mushroom, then you can try doing it differently. In this case, we will need a regular screwdriver or better yet two. The main thing is that they are not “cross-shaped”, moderately thin and relatively durable. We go to the rear window and very carefully insert a screwdriver under its seal. I would advise doing this in the place indicated in the picture.

Together with rounding the corners of the window, the screwdriver should go through. The most important thing is to take your time and act carefully so as not to damage the window seal. After the screwdriver has gone inside, you need to carefully press the window in your direction, using your other hand to help pull the seal. In the worst case, when opening the VAZ 2109 you will damage the glass seal, but not so much that you will not be able to put it back. However, you will have to replace it when the opportunity arises.

Method 3

Using this method, you will definitely not be able to open your VAZ 2109 without damage. If none of the previous methods worked for you and your car has a trunk lock cylinder, then you can try this method. You need to find a good flat head screwdriver that is powerful enough. We insert a screwdriver into the trunk lock cylinder and sharply try to turn it in the opening direction. If you are strong enough and do everything sharply, the lock will turn and access to the car is free. Unfortunately, this method does not always help.

Method 4

This method has not been tested by the author, but was found on the Internet and tested by other car owners. If your car does not have a rotten trunk lid and a standard lock is installed, then all you need to do is pull the trunk lid sharply towards yourself and up. The probability of damage to the cover in those places that you will hold on to is quite high if the cover is not new. But usually, almost any VAZ 2109 opens using the first two methods.

Keep an eye on the condition of the car and don’t forget the keys in the cabin - then you won’t have to learn how to open the car without a key.

Adequate methods

This will surprise many, but there are much more adequate methods to get into an automatically locked car without damaging it than radical and expensive ones.

So, the car is locked from the inside with the keys in the ignition, it’s a long drive to get the keys, and I don’t want to spend money either on a special company or on subsequent repairs:

1. Open the trunk to get into the cabin. There are several methods to perform this task:

• We apply a strong impulse blow with an open palm just below the lock, and the vibration will complete everything for you and the latch will open;
• take an awl (a woman’s nail file or manicure scissors) but not a screwdriver. We insert the existing object under the seal and press the tongue.

2. Open the hood and disconnect the battery. This is the simplest of the methods:

• we crawl under the car and find the cord leading to the hood lock; if that doesn’t work, we look for the lock tongue through the radiator grille;
• press the tongue mechanically or pull the cable and the hood opens;
• We approach the battery and knock down the negative terminal, and click it several times on the mount. The car body, which is a minus, is a large consumer and turning it on abruptly will create a small soft drop. It’s better not to touch the right one, because you can burn the ECU.

3. Open the door with wire. The sequence of actions is as follows:

• we find a stiff wire and an analogue of a woman’s nail file and get to work;
• use a thin object to pry out the glass seal near the lock;
• we insert the pre-bent wire into the prepared hole and lower it until it rests;
• the wire rests against the lock latch, so we turn it and turn it until it goes around it, when it “falls through” we pry it back;
• The opening procedure will take 2-5 minutes, and the door will be open; all that remains is to hammer the seal back.

4. Open with your phone. The most interesting, and most importantly effective method of how to open the door on a VAZ 2114. It is simple and amazing:

• you need to remember who has the second keys and call this person;
• bring the phone closer to the keyhole;
• the interlocutor at the other end presses the open button and the machine is open.

We reanimate the torsion bars of the VAZ-2115

We won’t discuss the car’s designers and guess what they were guided by when they decided to adapt such unreliable devices to support the massive trunk lid of the VAZ-2115. It’s better to talk about how to find a way out of this situation.

Method 1

As is customary in any civilized society, a car enthusiast, having discovered a malfunction, will, of course, try to find the right part in a car shop. But in this case, failure awaits him in advance: it is very difficult to find torsion bars on sale, and if there are no familiar craftsmen from a car service center, then you can bury the idea of ​​​​making them. If a miracle happens, and the necessary copies are found on sale, then there is no chance at all of installing them on the VAZ-2115 without the help of a specialist. It is necessary to remove the rear seat, dismantle the shelf, take measures to ensure that the trunk lid is open during the entire installation process... In general, if you like to overcome obstacles, this is your finest hour!

DIY parts repair

Method 2

Craftsmen with experience working with metal have found their own solution, which is effective, but completely unacceptable for those who are only used to riding. The point is this: the torsion bars used in the trunk of the VAZ-2115 have a twist of only half a turn around their own axis. If you tighten them one more turn, the problem will be solved. The only question is, do you know how to create sufficient force with the help of improvised means to carry out such an operation? That's it...

Method 3

A more accessible way is to adapt the clutch springs by attaching one end to metal plates installed with self-tapping screws on the trunk lining, and the other to the lid. This, of course, is a more suitable plan, but it also has its own unpleasant moment. Firstly, the skin is not a very reliable basis, and it is better to attach the strip to the body. Here, too, you need to act skillfully so as not to drill unnecessary holes. Secondly, the springs are still not suitable for working with the trunk lid of the VAZ-2115 and have the unpleasant property of stretching. Of course, these are not torsion bars, and replacing them will not be so difficult, but it is unlikely that any car owner wants to rack his brains and spend money once again.

Installing springs

Method 4

Another “invention” is the installation of gas shock absorbers instead of torsion bars (or in parallel with them), which are used in the trunks and rear doors of some cars

Here, too, it is important to think through everything, especially how to attach the devices to the car body. The disadvantages in this case are that two shock absorbers create such resistance, to overcome which you will have to apply significant force every time you close the lid of your VAZ-2115, and if you leave one shock absorber, there is a risk of its distortion

Installation of gas shock absorbers

Experts who specialize in car upgrades can offer many more methods, but each of them has its own advantages and disadvantages. Well, what about the reliability of the trunk lid of the VAZ-2115 classmates?

The trunk lid and its weaknesses

Among people living in Russia, there is an opinion that our auto industry creates, to put it mildly, not very high-quality cars. Perhaps this point of view is too biased, but it is an indisputable fact that owners of domestic cars sooner or later have to spend personal funds on car service. You can go into lengthy discussions about how it was before and how it is now, but many VAZ-2115 owners have already encountered a similar problem.

Sometimes a car brings a surprise not in the form of a breakdown of the chassis, transmission or engine, but in the form of a petty and nasty thing called a malfunction of the trunk torsion bars. For those who don't know, a little explanation. Torsion bars are shafts made of elastic material (or metal) that perform the same functions as shock absorbers or springs. The trunk lid in the “tag” is entrusted to be controlled by these devices.

During their service life, torsion bars tend to “loose their grip,” which is why while driving you can hear extraneous sounds and knocking coming from the depths of the trunk of the VAZ-2115. This is especially noticeable when driving over bumps. Due to insufficient traction, there is an additional load on the lock, and if you do not pay attention to the diagnosis of “little things” in time, you can see in the rearview mirror while driving how the luggage compartment lid copies the movements of a bird’s wing, taking off cheerfully at the moment the car hits an uneven surface.

How to remove an old lock

The process of removal and replacement on hatchback (2113, 2114) and sedan (2115) cars is different, although the principle of operation is the same.

The procedure for removing the mechanism on a VAZ-2114:

1. Remove the plastic cover. The upholstery is attached to 10 pistons, which just need to be pryed off with a screwdriver. Access to the mechanism will open.

Removing the trunk lid

1. Unscrew the 2 bolts with an “8” key. The action must be carried out carefully; on one side there are terminals responsible for the windshield wiper and brake light on the spoiler.

Unscrewing 2 bolts

1. Remove the faulty element.

If the lid does not close, adjustment is required.

:

1. Remove the plastic cover by unfastening the pistons.
2. Access to the faulty part is open; the drive rod needs to be straightened. Unscrew the corresponding screw (not all the way). Remove the rod from the bushing.

1. Go to the cylinder lever. Remove the mechanism rod and remove it.
2. Unscrew the 3 nuts of the product and dismantle it. Unscrew the cylinder mounting bolt and remove.

Renault Logan device?

Renault Logan trunk - thanks to it, this car was able to overtake many competitors in popularity. Its displacement was developed taking into account the possibility of loading large cargo. To achieve a truly record-breaking luggage compartment capacity without compromising driving performance and passenger comfort, a truly gigantic amount of work was done! The changes affected not only the internal space. Thus, the height of the trunk lid was reduced, and its upper part acquired a kind of “superstructure”, reminiscent of a spoiler.

Replacing the trunk lock on a VAZ-2113 2114 2115

The old mechanism has been removed, a new one needs to be installed. The process is the reverse of dismantling.

The cylinder is replaced with the lock removed. You need to check the condition of the spring. If the element is weak, it needs to be replaced.

When installing a new element, you do not need to immediately tighten the bolts - the trunk will not close. It is recommended to adjust the position of the cover using the latches. The bolts are tightened slowly. This will allow you to make adjustments so that the lid closes tightly. You need to check the seals. When the elements wear out, the cover hits the body, creating vibrations.

The trunk lock of the Lada Samara family often fails. One simple modification will solve the problem. It is enough to install the product from Lada-Granta.

The process is as follows:

1. Make a mount from a 40 x 40 mm corner.

1. Install the cylinder plug on the lid.
2. Connect the wires. “Power up” from the elements going to the wiper. One wire (white with a blue stripe) is connected to the lock drive, the other (yellow with a blue stripe) is connected to the limit switch.
3. Install a new product, adjust it, make sure it works.

After these steps, we get a reliable and durable mechanism that will not open on its own and will not rattle.

Before starting work, you need to disconnect the (-) terminal from the battery for safety.

Disconnecting the terminal from the battery
