If you’re having electrical issues with your Volkswagen Jetta, it might be due to a blown fuse. The fuse box on a Volkswagen Jetta is located under the dash on the driver’s side, near the pedals. In this article, we’ll provide you with a fuse diagram for the Volkswagen Jetta, and answer some frequently asked questions related to the Jetta’s fuse box.
What is a Fuse?
A fuse is a safety device that protects electrical circuits from overloading. When an electrical current exceeds the limit of a circuit, the fuse will “blow” or burn out, breaking the circuit and preventing any further damage or overload.
Fuses are found in many different types of electrical devices, including cars. In a Volkswagen Jetta, the fuse box contains a number of fuses that protect various electrical components, such as the radio, headlights, and air conditioning system. If one of these components isn’t working, it’s possible that the corresponding fuse has blown.

Frequently Asked Questions
1. How do I know if a fuse has blown in my Volkswagen Jetta?
If you’re experiencing electrical issues with your Jetta, it’s possible that a fuse has blown. To check, locate the fuse box on the driver’s side of the dash, near the pedals. Use the diagram above to find the corresponding fuse for the component that isn’t working. If the metal strip inside the fuse is broken, the fuse has blown and needs to be replaced.
2. How do I replace a blown fuse in my Volkswagen Jetta?
To replace a blown fuse in the Volkswagen Jetta, follow these steps:
- Locate the fuse box on the driver’s side of the dash, near the pedals.
- Use the diagram above to find the corresponding fuse for the component that isn’t working.
- Using a fuse puller, gently pull the fuse out of the fuse box. If you don’t have a fuse puller, you can use a pair of pliers.
- Inspect the metal strip inside the fuse. If the strip is broken, the fuse has blown and needs to be replaced.
- Insert a new fuse of the same amperage into the slot where the blown fuse was located. Make sure the new fuse is inserted all the way in.
3. What should I do if I can’t find the problem after replacing a blown fuse?
If you’ve replaced a blown fuse in your Volkswagen Jetta and the electrical issue persists, it’s possible that there’s a more serious problem with the electrical system. In this case, it’s best to take the car to a qualified mechanic for diagnosis and repair.
4. Can I use a higher amperage fuse than recommended?
No, you should always use the recommended amperage for each fuse in your Volkswagen Jetta. Using a higher amperage fuse could result in damage to the electrical system and could even cause a fire.
5. What should I do if a fuse keeps blowing?
If a fuse keeps blowing in your Volkswagen Jetta, it’s likely that there’s an underlying electrical issue that needs to be addressed. Again, it’s best to take the car to a qualified mechanic for diagnosis and repair.
