How to make an electric trunk drive with your own hands? when you want comfort

Car owners often strive to improve the functionality of their car. Installing an electric rear door, if it is not provided by the manufacturer, greatly simplifies the process of opening/closing the trunk. You can do this yourself.

Even the seemingly most advanced factory equipment of a car cannot always fully satisfy the needs of its owner. Car owners often strive to improve the functionality of their pet, for example, by installing a convenient electric rear door. This mechanism greatly facilitates the process of closing and opening the trunk. Such devices often perform similar functions on the side doors of the car, and are also used to control the power windows.

In our country, such improvements are mainly resorted to by the owners of classic domestically produced models: VAZ, Moskvich, Volga and others. But it happens that you need to install the electric trunk drive yourself on a foreign car, for example, Geely Atlas, Volkswagen Touareg or Skoda Rapid. The modern market provides ample opportunities to eliminate almost any functional gaps left by automakers for one reason or another. You can also independently replace an outdated electric trunk drive with a newer and more efficient model or repair faulty equipment.

Luxury or necessity

The automatic trunk opening feature is found in many new cars. Drivers like this feature, because you quickly get used to good things. To open the luggage compartment in a car, just press a button in the cabin. The lock comes into operation as a result of the operation of the electric drive.

This feature may seem like a small thing and an insignificant addition until the cold weather arrives. In cold weather, the lock on the trunk often freezes, making opening the compartment a difficult task. You have to spend time defrosting the mechanism. In the case of an electric drive, such problems will not arise. Also, such a mechanism makes car hacking more difficult, which is also an important advantage.

Mostly imported cars are equipped with this function, and not all of them. Domestic manufacturers have only recently begun to equip their models with such functionality. Every car owner can equip his car with an electric drive for the trunk. This will not be difficult to do, but you will still have to tinker.

Chevrolet Cruze trunk button: replacement, repair. Button output to the salon

During vehicle operation, breakdowns or unforeseen incidents with the vehicle’s equipment are common. One of these unpleasant cases is the breakdown of the trunk button of a Chevrolet Cruze car.

Below in the article possible breakdowns of the unit and ways to fix it are indicated.

Reasons why the button does not work

The trunk release button on the Chevrolet Cruze model breaks due to its extremely poor location. An engineering miscalculation in the form of installing an element on the outside of the car exposes the part to constant exposure to an aggressive environment.

During operation, the digger often gets exposed to water, dirt or snow. This leads to rapid destruction of the seals. Sometimes it happens that a trip to the car wash can also lead to a breakdown.

The main reasons for node failure are the following factors:

Oxidation of the contact group located inside the key. As a result, the element’s response to driver manipulations deteriorates.
Short circuit of contact pairs. If liquid or dirt gets in, the working contacts may inadvertently close. In the future, for this reason, the unit may be triggered randomly and the trunk will open.

The basis for such problems is two questions:

bad location;
mediocre sealing of the unit.

Replacing the trunk release button

The replacement procedure is applied in case of failure or revision. Sometimes repairing a broken key is limited only to replacing it.

The process itself is technically simple. To do this you will need to perform the following steps:

Use the key to open the trunk lid.
Next you need to remove the fasteners from the casing. There are a total of 12 plastic elements, which are very capricious when applying force. They may break. Therefore, you need to remove the fasteners very carefully.

The protective cap of the lock is removed from the end of the trunk lid. The procedure is performed extremely carefully - the plastic is delicate and is afraid of sudden movements.

The next step is to dismantle the casing.

Next, using a “10” key, you need to unscrew the fastenings of the license plate illumination mounting plate. The same part has a button on it.

The key terminal block is carefully disconnected. Remove the rubber seal for the electrical wiring from the cover. Remove the decorative strip. The element is fastened with two plastic latches. The procedure can be easily accomplished using a very thin screwdriver or similar tool. It is recommended to exercise great care during work, as there is a possibility of damage to the paintwork at the point of contact.

Replace old elements with new ones. Some experts recommend upgrading moisture protection by applying a layer of sealant.

Assembly must be done in reverse order.

Device Features

To open the trunk remotely, automakers use two main methods. The first involves installing an electric drive in the cover, and the second involves the use of pneumatic drives. The latter option is considered more reliable, but also more expensive.

The lid can also be controlled using an electric drive in various ways. This can involve buttons on the dashboard, buttons on the doors, handles on the trunk itself, and remote controls. Each option, in principle, looks attractive and potentially convenient. Therefore, the motorist needs to decide for himself what kind of result he wants to get. It is important to understand that the remote control is convenient, but it can be easily lost. Plus, the installation involves a very complex set of works. Because of this, the most optimal option is to locate the button inside the car interior.

The electric drive device includes several main components. The drive with an electric motor is quite practical, reliable, durable and hardy under active conditions. Less commonly, you can find drives that use magnetic plates. The design is more complex and can create a number of additional problems. It's better not to use them.

The undeniable advantage of the device is that it is quite possible to install it yourself, and on almost any car. If you read various forums, study the work of various craftsmen, of which Moscow alone includes several hundred, as well as the whole of Ukraine, you can see clear examples of the implementation of electric drives on a wide range of car models and brands.

For clarity, I will give several examples where such a system is available from the factory or can be installed on your own:

Audi Q5;
Kia Optima;
Mercedes W211;
Volkswagen Touareg;
Chevrolet Niva;
VAZ 2170 (Priora sedan);
Lada Vesta SV;
Ford Kuga 2nd generation;
VAZ 2114;
VAZ 2115;
VAZ 2104;
Lada Granta;
Skoda Superb, etc.

There really are a lot of options. It is almost impossible to list everything. That is, you understand that you can install an electric trunk lid on any car.

Criteria for choosing an electric lock

When buying an electric trunk lid, you need to take the choice seriously. Our market offers customers many different devices in different price categories, but it is better to immediately exclude cheap options. Such a unit will not be able to work for a long time, because the low price, as a rule, is due to the same quality of production of the device. Therefore, immediately exclude Chinese options - in this case it is better to give preference to Russian or imported devices.

Principle of operation

Typically, the operating principle of the fifth door electric drive is quite simple. To understand it, it is highly advisable to arm yourself with the diagram that is included in the kit and be able to personally observe the operation of all moving components.

The rod is connected to the electric motor using a worm gear. This allows you to avoid several problems at once: firstly, the metal worm, unlike a rubber belt, practically does not wear out even with prolonged use. Secondly, the use of a metal component makes it possible to withstand the weight of the lid, which sometimes exceeds a hundred kilograms.

The motor, depending on the polarity applied to it, can also work for closing. To do this, using the relay included in the kit, you can change the direction of the electrical pulse that is applied to the system.

The mechanism is necessarily supplemented with a control unit. Schematically, this block consists of two parts. The first part receives a signal from the key fob: it is understood that when you press a button on the key fob, the control signal reaches the computing circuit through a diode, where it is processed and converted into a pulse for the electric motor.

The second part of the mechanism is the computing center, whose task is to distinguish between drive movement signals in both directions and filter them from extraneous signals and interference. If we are talking about a button installed in the cabin, then it does not have a wireless principle of operation, and it is connected directly to the drive. This makes it much easier to install such a lock on a car and reduce its cost.

Benefits of this option

Many people do not find anything special in this option, but once you try the electric trunk drive, you immediately begin to appreciate all the advantages. The positive aspects of the option to automatically open the trunk on the VAZ-2107 include:

Convenience. By the time the driver leaves the cabin, the trunk will already be open.
Practicality. There is no need to remove the keys from the ignition switch to open the trunk with the key, especially if you have just started the engine and are warming it up.
Fashion. Almost all modern cars are equipped with such an interesting option, so the “seven” with this function will look more interesting against their background, especially with tuning.

Next, we’ll look at what the procedure for installing an electric drive for opening the trunk on a VAZ 2107 is with your own hands.

What is required for the work

Before starting the work process, you should purchase the necessary equipment. To carry out the work you will need:

A button that, when pressed, will activate the electric drive. The best option is a button from a VAZ-2110 car, the cost of which is about 50-80 rubles.
The relay is four-pin and has a special terminal for it.
Activator.
Wires.
Female and male connectors, as well as electrical tape and heat shrink.

You can easily find any of the components in any auto store, and then install and connect it to your car yourself.

Installation of the activator

Initially, it is necessary to install an activator, which is an electric drive that works to retract or repel, depending on the connection. The first step is to remove the lock and install the activator rod. To remove the lock, you will need to unscrew two nuts.

After this, you need to drill a hole in the side of the lock to insert the rod and connect it to the lock tongue. The rod will need to be bent (secured), it should look something like the one shown in the photo below.

After fixing the rod to the lock, the latter can be installed in place. It is advisable to remember the tilt level of the lock and install it as well, so that you do not have to adjust it during installation. Now you can attach the activator to the trunk. To do this, you will need 2 self-tapping screws and a special plate, which comes with the product. After this, you can manually try to see if the lock will work when opening. When the activator is installed on your VAZ 2107 car, you can proceed to the next stage - connection.

Connecting the product

Before carrying out connection work, be sure to disconnect the negative terminal from the battery. To begin with, we present the diagram according to which the product will function.

The electric lock will be supplied with 12V power directly from the battery, although you can also use a wire from the cigarette lighter. First, connect the wire to the “+” terminal of the battery.

The battery supplies power to the relay, which can be located both in the cabin and in the engine compartment, which will be much more rational. From terminal “86” the wire is fed to the trunk opening button, which can be located in any convenient place on the dashboard. To install the button that will open the trunk lid, you will need to drill a hole of the appropriate diameter in the dashboard.

First installation option

In order to implement the design, you can use two methods. And the very first is the purchase of standard products designed for electric trunk drive. It's best to take extra. The components of the system must be reinforced, the materials used for their manufacture must be of only high quality. Of course, the cost of such a set will be rather high, but you will be sure that it will serve you for many years and will not break at the most inopportune moment. The presence of an inertial mechanism is welcome, since it is with its help that the drive will be turned off if there is an obstacle in the path of the trunk lid movement.

Installation

I can’t say that installing an electric drive is something incredibly difficult. In fact, anyone who knows how to work with bench tools, a soldering iron, and also knows the difference between transistors and diodes can implement such a mechanism.

The installation process roughly looks like this:

Many car enthusiasts who independently “pump” their cars are wondering: how to properly connect the electrics? This question arises in almost any installation. After all, simply screwing on blocks, locks and strips is not difficult, but only properly connected electricians can make the system work

If we take into account one of the most pressing problems - the installation of remote control locks for the fifth door, then the correct wiring diagram for the electric trunk lock will help us here. You can find it either in the instructions that should be included with the device, or you can take it from a reliable source, but it is better to use proven options and ask friends and acquaintances what scheme they used

Electric trunk drive: which is more reliable, factory or self-assembly?

Before implementing any idea, you should think carefully and prepare everything you need. In a situation with an electric trunk drive, first of all, you need to purchase the mechanism itself. Today, this is not a problem, because it is easy to find in virtually any auto parts store. Very often, all such electrical mechanisms, depending on the manufacturer or other minor design features, differ from each other, but the operating principle remains the same.

Therefore, some car enthusiasts assemble the required mechanism at home, but for the greatest confidence that the end result will be positive, it is advisable to purchase a ready-made device.

The opinions of the service station masters agreed on the choice of manufacturer - there is not much difference. When purchasing original products, the service life of the equipment exceeds 5 years. Installation in “makeshift” conditions and poor-quality manufacturing only shorten the period of use of the equipment. Often the owner is to blame for the breakdown, violating the vehicle maintenance regulations.

Additional modernization of locks

If you dream of your car doors opening and closing as smoothly as in foreign cars, try installing silent locks. Such a device can be installed on any model of Zhiguli. For representatives of the retro era, such modernization is also possible, but the locks themselves will have to be filed a little. By the way, you can also put it on the trunk. In general, there is no limit to perfection.

Silent locks

And the installation is, in truth, very simple and transparent. It is enough to dismantle the old locks, try not to drop the necessary elements inside the door, or remove the trim in advance. And then install new analogues on two bolts. There are situations when, after installation, the door does not close tightly or warps slightly, causing cracks to form. Solving the problem is also very simple by adjusting the location of the device. In general, initially try to secure it exactly where the old one was.

Why can we help better?

If the electric drive itself and the principle of its operation can be called simple, then its installation is not. You definitely need experience and skill to do all the work quickly and with the highest quality. This is especially true for those cars for which such an option was not provided.

The Argument-Auto car service will help everyone who wants to install an electric trunk drive on their car. We will not only be able to do all the work discreetly and efficiently, but we will order and deliver all the necessary equipment. We will do this at reasonable prices.

Come to us and you will receive:

Trunk lid electric drive device

As already mentioned, depending on the type of electric drive, the mechanism will also differ. For example, let's look at the simplest and most complex kit, as well as their main differences. After all, it is precisely because of the differences and configuration that the price of the mechanism will differ.

The simplest is considered to be an electric trunk lid, which opens and closes only with a button in the car interior. The kit of such a system includes a control unit, a button, trunk lid closers and two movable rods. If we talk about top-end electric drive options, then in addition to the basic set (the simplest mechanism), the manufacturer added sensors under the rear bumper. The ability to open from a button on the control panel, and the software of the control unit has also been improved for access from a smartphone.

If the button and control unit are clear, then how the trunk lid electric drive mechanism itself works, which, in fact, performs physical actions. Externally, the movable rod, or as manufacturers sometimes label it, a telescopic rod, at first glance is not particularly different from a gas rod, which can also be installed by the factory, unless, of course, you compare the thickness of the rod itself. There are a lot more differences inside.

For symmetry and reliability, it is customary to install two telescopic rods on the tailgate. On the one hand, it is beautiful, but most importantly it is reliable, since the door hinges will not warp or break due to uneven load. The rod itself (telescopic rod) consists of:

Two-stage gearbox;
Spring based brake;
Movable screw nut;
Spring;
Drive motor;
Lead screw;
External body of the telescopic rod;
Hall Sensor.

It is this mechanism of the telescopic rod that is considered the main or central one in the entire scheme. The size of the parts may vary depending on the brand, make and model of the car, but the basic principle of operation is unchanged, and for the most part the same for all cars.

How to remove saffron milk caps from a car body quickly at home

It is necessary to modify the purchased mechanism, remove the motor and rotate it so that it can function along the rack. Using a grinder removes all excess;
Using a perforated metal blank, a fastening strip is made from it;
The rack and drive motors are fixed to the bar. This design is mounted on body panels;
One end of the window regulator mechanism, which was not used, is mounted on the trunk lid holder;
Then everything is adjusted together and brought to the desired position;
Think in advance about how you will lay out the wiring harness so that the wiring does not fray or become damaged;
The connection diagram is selected based on the selected set. Ready-made kits have a special scheme, that is, you need to act strictly according to it;
Connection to the power source is carried out with a separate cable, which is connected to the battery;
A separate fuse is used for the power circuit;
A button is mounted in the cabin in a place convenient for the driver.

In terms of ease of installation, it is much more convenient to work with ready-made factory kits. The manufacturer includes detailed instructions, following which you can do everything in just a couple of hours and enjoy the result.

Whether the financial and time costs are worth it, everyone decides for themselves. After all, before we somehow managed without an electric drive on the trunk. You can continue to live without him. And if you want, then no one forbids or prevents you from installing the kit.

Electric drive connection features

Now that all the wires are in place, you can connect them to the control unit. Try to maintain polarity so that the semiconductor elements do not fail. Experts recommend using a separate cable for connection, which must be connected to the battery through a fuse.

The wire cross-section and fuse rating depend on the power of the drive. If you are using a universal electric trunk drive or for a specific car brand, it is best to install the control buttons at the bottom of the dashboard. But only in such a way that when driving you would not be able to accidentally catch it.

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:

Make a mount from a 40 x 40 mm corner.

Install the cylinder plug on the lid.
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.
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

Second implementation method

And the second method is the most interesting - you assemble and install all the components of the electric trunk lock drive yourself. In this case, you use partially finished elements. As a rule, many car enthusiasts install electric drives made on the basis of some standard mechanism. It is imperative to use inertial mechanisms so that if there is an obstacle in the path of the trunk, the electric motor does not fail.

When using a simple motor, it will fail if there is an obstacle - voltage will continue to be supplied to the windings, and the rotor will stand still. As a result, the windings simply burn out.

The principle of operation of the trunk opening and closing mechanism

Such a mechanism consists of a small number of parts:

motor;
a pair of four-pin relays;
push rod;
fuse;
button to control the mechanism.

Installed tailgate servo

The drive responsible for the operation of the rod is available in two varieties. A more common option is a mechanism with a motor. It is highly practical and durable, which explains its popularity. The magnetic platter drive has not received such wide demand because it is complex and problematic. Its operation is based on the interaction of a relay with magnetic plates.

As a result of power supply to the relay, the rod is pulled back, which leads to the opening of the trunk lid. Old VAZ models are not designed for such a mechanism. On such cars, such mechanisms turn out to be impractical. During the installation process, you will have to carry out complex modernization, which often turns out to be irrational.

Kit selection

Installation will not be possible if you do not have at your disposal a set of equipment necessary for installation. Buying it is not difficult, but you need to think about which specific option is best for you.

In total, 2 solutions to the current situation are being considered. Namely.

Factory set. Purchased from trusted and reputable manufacturers. The kit contains almost everything you need, so you don’t have to assemble different elements. But the price is naturally higher;
Amateur kit. Here we are talking about independently preparing all the necessary components. The motorist is faced with the question of where exactly to get them and how to choose a set so that everything fits. It is difficult to do this without relevant experience and certain knowledge. But you can save a lot of money financially.

I don’t know what exactly you will choose, but I want to give one piece of advice. Buy an electric drive equipped with an inertia mechanism. This will allow you to turn off the drive when an obstacle appears in the path of the luggage compartment lid. Roughly speaking, the drive will not pinch your hand or head when you poke around in the trunk.

So the inertial mechanism is a very useful thing.

If we talk about assembling a homemade kit, then it is important to collect several basic elements. These include:
