Volkswagen Golf 2 (Jetta 2) - fuses and relays

Volkswagen Golf 2

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.

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.

Video “Indicator fuse, demonstration of operation”

In this video you can clearly learn about the safety devices in the Volkswagen Jetta.

Almost the entire system of Volkswagen Jetta power circuits, on which the operation of the vehicle’s equipment depends, is protected by fusible contact elements, which are combined into a so-called fuse block. Through relays, which are also included in this block, such energy consumers are connected as:

• lighting lamps;
• electric cooling fan motors;
• fuel pump, etc.

This unit and its serviceability are of particular importance for the stable operation of the main systems of the Volkswagen Jetta model. That is why these contact elements are combined and placed in a special mounting block. According to the instructions, it is located in the interior of the Volkswagen Jetta, on the left side of the instrument panel. There is a top shelf, which in turn consists of:

1. lower casing of the instrument panel;
2. fixing screw;
3. instrument panels;
4. cover protecting the unit.

This is where the block is located, where in case of a malfunction you need to look. As a rule, a faulty or burnt-out contact element will give itself away. It will have a melted metal part with a black coating. It is also possible that the colored case will be distorted.

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.

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.
