Volkswagen Jetta A4 Fuse Box Diagram [2000-2005]

The Volkswagen Jetta A4 was produced from 2000 to 2005. During this time, two fuse boxes were used in the vehicle: one in the engine compartment and one in the passenger compartment.

The fuse box in the engine compartment is located on the left side of the engine bay, near the battery. It contains fuses for the vehicle’s engine, electrical system, and other major components.

The fuse box in the passenger compartment is located under the left side of the dashboard. It contains fuses for the vehicle’s interior accessories, such as headlights, power windows, and radio.

This article provides fuse box diagrams for both the engine compartment and passenger compartment fuse boxes in the Volkswagen Jetta A4. The diagrams show the location of each fuse and relay, as well as the amperage rating of each fuse.

Note: It is a good idea to keep a supply of spare fuses on hand. They are available from your authorized VOLKSWAGEN dealer.
