Fuses and relays Mazda 6 GH (2007-2012) with decoding

Mazda 6 GH cars belong to the second generation of production (2007, 2008, 2009, 2010, 2011, 2012) and have an engine capacity of 1.8 l, 2.0 l, 2.2 l, 2.5 l and 3.7 l. In the Mazda 6 gh there are two main mounting fuse and relay blocks, located under the hood and in the passenger compartment.

The car was presented in three body styles: sedan, hatchback and station wagon.

In this article we will look in detail at where the fuse and relay blocks are located, their circuits and purpose. We especially highlight the washer and cigarette lighter fuses.

Depending on the year of manufacture, modification and equipment of the car, the pinout of fuses and relays may differ, check the assignment with the cover

Fuses in the cabin

The Mazda 6 GH interior fuse box is located on the left side of the dashboard, below the steering wheel, in the side pillar. To access the unit, you need to remove the protective cover by prying it off with your fingers.

The cigarette lighter fuse is number 5 with a current of 15 Amps. The remaining sockets for additional equipment are protected by fuse number 13. The headlight washer is located in the block under the hood - number 21 for 20 Amperes (see below).

Reasons for fuses failure on Mazda 6

• Failure to comply with technical inspection regulations,
• Purchase and installation of non-original components
• Unprofessional installation
• Mechanical damage to the mounting block, accident, impact, collision,
• Violation of the integrity of the insulating layer of electrical wiring,
• Short circuit in the circuit,
• Loose terminal contacts,
• Oxidation of terminals,
• Formation of condensation, moisture ingress into the mounting block,
• Manufacturing defect.

Fuses and relays under the hood

They are located in the engine compartment between the battery and the left wing of the car. You can open it by pressing the special latch at the top of the block.

Location and access to the unit under the hood

You should know that in this unit under the hood there is also a fuse and a relay that are responsible for the operation of the cigarette lighter and additional sockets (see Prev. No. 14 for 25 Amps and Relay No. 8).

For your information:

• There is no separate fuse for the license plate light in the Mazda 6 gh (if all other lamps are on, then you should look for the reason in the wiring).

Description of fuses on a Mazda 6 car: location, diagram, price

In Mazda 6, regardless of the generation GG, GH, GJ, knife-type fuses with a melting element in the center are pre-installed.

A set of new original modules starting at 3,000 rubles. High-quality analogues from 2300 – 2500 rubles. Individual fuses from 200 rubles.

Recommendations for servicing the mounting block

• Check the condition of the fuses periodically and replace them with new ones as necessary.
• After long trips through puddles or in the rain, check for moisture and condensation in the mounting block. Dry the board with a stream of compressed air,
• If the mechanism suddenly stops functioning, do not rush to replace it with a new one. Check the module status, use a multimeter to diagnose.

Despite the simplicity of the design of the mounting block, carry out diagnostic work at a service station. Unprofessional intervention in repairs leads to undesirable consequences.

Replacing fuses on a Mazda 6

Preparatory stage: no tools are needed, since there is no need to unscrew anything.

Sequencing:

• We place the Mazda 6 on the platform, block the rear wheels with wheel chocks, and squeeze the parking brake;
• To replace modules in the cabin, you need to open the front passenger door. On the right side of the central channel there is a technological hatch;
• Carefully open it and look at the layout of the modules. We remove the fuse by serial number. The location diagram is indicated on the back of the cover;
• We check the current indicator (amperage) with the data specified in the instruction manual.

Note to the driver!!! It is unacceptable to install fuses with higher or lower current strength. In both cases, this will lead to failure of the equipment that is assigned to the module.

• If you need to replace the entire mounting block in the cabin, you will need a Phillips head screwdriver. We unscrew two screws, disconnect the contacts from the board, remove it from its regular place;
• We carry out preventive maintenance, replace worn elements with new ones, and assemble the structure in the reverse order.

Algorithm for replacing relay switches in the engine compartment of a Mazda 6 car

• Open the hood, stop the engine, remove the power terminals from the battery;
• On the right side under the hood, closer to the frill, there is a mounting block with power relays;
• We remove the faulty element, having first checked the location according to the diagram indicated on the back of the plastic cover.

We install new modules, close the lid, check that the units are working properly, and start the engine.

The average service life of fuses is 45 thousand km.
