แ… Volkswagen Jetta (2003 - 2009) Fuse Box Diagram ๐Ÿ”ง (2024)

FAQs

Where is the fuse box in a 2003 VW Jetta? โ€บ

The first step is to check the fuse for the stereo, it's #42 in the illustration below...the fuse box is on the left of the instrument panel. Fuses from S24 to S44 are identified with additional prefix 2, in wiring diagram. Example: Fuse S40 on fuse panel is listed as S240 in wiring diagram.

Where is the internal fuse box? โ€บ

Usually, you will find two fuse boxes in the car. One is located under the hood and the other is found in the dashboard or near the steering wheel.

What are the main fuses in fuse box? โ€บ

Your fuse box will have two sets of fuses. At the bottom will be 15-amp and 20-amp screw-in fuses with glass faces that are exposed and visible. These fuses will service branch light circuits and outlet circuits. At the top will be 30-amp or 40-amp cartridge main fuses for ovens, laundry rooms, or stoves.

Where is the secondary fuse box? โ€บ

The secondary under-hood fuse box is next to the battery. To open it, push the tabs as shown. If something electrical in your vehicle stops working, check for a blown fuse first. Determine from the chart on pages and , or the diagram on the fuse box lid, which fuse or fuses control that device.

How do I know which fuse is blown in my fuse box? โ€บ

Remove the fuse from its holder. In some cases you may need a small screwdriver to unscrew the fuse holder cap. Look at the fuse wire. If there is a visible gap in the wire or a dark or metallic smear inside the glass then the fuse is blown and needs to be replaced.

Which fuse is the dashboard? โ€บ

Which Fuse Controls the Dashboard Gauge? The instrument cluster fuse manages the dashboard gauge of a vehicle. It uses electricity from the car battery to power various electronic components of the dashboard such as the different warning lights, gauges, and alarm systems.

Where is blown fuse located? โ€บ

Usually, it will be in your garage or your basement. Open the fuse box and look at the glass containers that hold the fuses. If you can see that the fuse is visibly broken, or there is metallic residue on the glass from the fuse blowing, you will need to replace that particular fuse.

Where can I check fuses? โ€บ

Typically, fuse boxes are located in basements, garages, laundry rooms, and attics. If you have trouble finding your fuse box, check the utility meter outside your home. Try to follow the wire that leads from the meter. Fuse boxes and circuit breakers are usually located near where power enters the house.

How many fuse boxes are in a car? โ€บ

Most vehicles are equipped with two fuse boxes. One is located in the engine compartment and is used to protect engine components such as the cooling system, anti-lock brake pump, and the engine control unit.

How to tell if a car fuse is blown? โ€บ

Still gripping it with the puller, hold the fuse up to the light (or a light source) and look through the translucent bodywork. You should see a thin metal wire in there. If the wire is no longer a continuous thread and appears broken or in two pieces, the fuse has indeed 'blown'.
