Volkswagen Golf 2 (Jetta 2) - fuses and relays

generation was produced with sedan and hatchback bodies not only in Germany, but also in the UK, Finland, Japan, the USA and some other countries of the current European Union. Years of production: 1983, 1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991 and 1992. The model underwent the most significant restyling in 1987. More than 6.3 million cars were produced on all continents. In this article you will find a description of the fuse and relay blocks of the 2nd generation Volkswagen Golf, with photo examples of blocks, their diagrams and designations of elements. Note the fuse responsible for the cigarette lighter. In conclusion, we will offer for download a book with a complete description of electrical circuits.

The number of elements in the main unit may differ from those shown and depends on the configuration, year of manufacture and country of delivery. The current purpose specifically for your car will be printed on top of the protective cover - the box. And if the generation is not suitable, study the description for the 3rd. We also note that the current schemes are suitable for the Jetta 2 model.

Removal and replacement

The replacement process is identical for all versions of the FV. To replace, you will need a screwdriver or wrenches, depending on whether the power supply is attached to the body with bolts or self-tapping screws. Decide which tool you need, and you can start removing.

1. Using a screwdriver, disconnect the dashboard trim behind which the power supply is installed in your car.
2. Unscrew the screws securing the power supply to the car body.
3. Pull out the device: it will hang on the wires.
4. Take the new power supply unit and, one by one, disconnecting it from the old device, insert all the necessary wires into the connectors of the new power supply unit.
5. Install the new power supply in place by tightening the fastening screws and closing the instrument panel trim.

Features of replacing fuses in Golf 2

Procedure

To replace an element in the fuse box in a Golf 2, you must follow the following procedure:

1. Remove the cover from the block.
2. Identify the faulty element by the melted walls and remove it using plastic tweezers.
3. Insert a new part in accordance with the pinout of the fuse box in Golf 2. The fuse must be designed for the same amperage, which can be determined by the color and special inscription on the holder.
4. Close the block with a lid.

If the new fuse quickly blows again, the corresponding electrical circuit must be carefully checked for overloads.

You cannot replace a damaged element with wire or other improvised materials. This may result in equipment failure or even a fire in the unit. For safety reasons, it is best to keep a small set of spare fuses in your car at all times. For this purpose, special fastenings are provided in the block.

Recommendations

Recommendations for replacement:

• Before starting work, it is advisable to turn off the electrical circuit in which the fuse has failed.
• It is not recommended to use grips that are too hard as they can scratch the contacts.
• If a constantly blowing fuse controls the operation of several circuits, you need to alternately connect one circuit to it and check it for errors. Only in this case will it be possible to find the true cause of the malfunction.
• Using a fuse with a higher amperage may cause damage or fire.

Fuses under the hood

On vehicles with diesel engines, the electrical power supply circuit for the glow plugs is protected by a high-power fuse in the form of a fuse link.

Leaky cylinder head gasket

This malfunction does not occur often, but, in addition to deteriorating the performance of the standard heating element, it threatens significant problems for the power unit. Diagnosing the problem is easy. If an antifreeze leak is accompanied by a change in exhaust color from clear to solid white, this indicates that fluid is entering the cylinders and then into the muffler. A leaking BC head gasket seal is a serious problem because coolant will also enter the lubrication system, reducing the viscosity of the engine oil, which can significantly reduce engine life. Therefore, if a malfunction is detected, the gasket should be replaced as soon as possible. This procedure is quite responsible, but it can be done independently. If you have no experience in disassembling the cylinder head, it is better to turn to specialists to avoid mistakes typical for beginners.

Faulty thermostat

A stuck thermostat valve is a sign of a malfunction in all cars without exception. Typically, while driving, the engine should warm up to operating temperature in no more than 10 minutes (in winter, idling may take much longer). If the movement of the valve is impaired, which is facilitated by the formation of scale on the internal walls of the thermostat, it begins to wedge and eventually stops moving altogether, and this can happen in an open, closed or intermediate position. Replacing the thermostat is a simple procedure, the main problem is to disassemble the pipes, since usually the clamp and the pipe itself stick to the fitting and you will have to tinker with their removal. Steps to replace the thermostat:

• unscrew the RB cap;
• place a container for antifreeze under the thermostat;
• remove the pipes;
• Using a 10mm wrench, unscrew the two bolts that secure the thermostat to the engine;
• removes the thermostat along with the gasket;
• wait 10-15 minutes for the coolant to drain;
• install a new part;
• refill with new antifreeze.

Additional fusible elements

In some versions of Volkswagen Golf 3rd generation vehicles, additional fuses may be used. The following additional elements are used in the interior fuse and relay module:

• rated 30A - power supply to the ABS system relay;
• rated 30A - power supply to the relay of the hydroelectric unit of the ABS system;
• rated 10A - air conditioning compressor for cars without climate control;
• rated 30A - interior ventilation motor with the ClimaTronic system;
• with a nominal value of 5A - controller of the ClimaTronic system;
• rated 5A - +12A power supply to the on-board network of a towed trailer.

For a diesel internal combustion engine, an additional PP for the engine warm-up system is used, with a rated current of 60 A. It is located separately, on the engine panel under the hood.

Checking the health of fuses

If the functionality of any vehicle device malfunctions, it is necessary, using Tables 1 and 2, to determine which fuses serve this element. Then you need to turn off the ignition.

In some cases (failure of the engine control unit, generator, side lights, cigarette lighter, etc.), it is better to remove the negative terminal of the battery. Then, using special dielectric pliers (you can use pliers), you need to disassemble the necessary fuses.

Testing fuses without removing them from the block may give an erroneous result.

Fuses in transparent housings can be checked visually. It should be remembered that this method of fault monitoring does not have a 100% guarantee, since sometimes it is not possible to see a microcrack in the conductive insert.

It is best to use the multimeter in the "diode", "resistance" or "continuity" test positions. The resistance value of a good fuse is approximately zero. The resistance of a blown fuse tends to infinity (the multimeter displays “1”).
