Where is the power window fuse located in an old Jetta?
3 Answers
Jetta's power window control box is located above the fuse box, installed on the inner side of the dashboard. Composition of Jetta's electric power windows: Electric power windows are mostly composed of a motor, reducer, guide rope, guide plate, and glass mounting bracket. Depending on the material or manufacturing process of the guide rope, they are divided into three types: cable pulley type, flexible shaft type, and plastic type. The first two types use steel wire ropes as the guide rope, while the latter uses a plastic belt as the guide rope. Taking the commonly used cable pulley type electric power window as an example, it consists of components such as a motor, reducer, steel wire rope, guide plate, and glass mounting bracket. During installation, the door window glass is fixed on the glass mounting bracket, and the glass guide groove is parallel to the steel wire rope guide plate. Usage of Jetta's power windows: Activate the motor, which drives the reducer to output power, pulling the steel wire rope to move the glass mounting bracket, forcing the door window glass to move in a straight line upward or downward. The plastic belt type electric power window uses a plastic belt as the guide rope, with holes on the belt for moving and positioning the plastic belt, controlling the rise and fall of the door window glass.
When the window regulator of my old Jetta had issues, it was a headache. Later, I found out that the fuse is located in a small box under the lower left side of the steering wheel, called the fuse box. Open the cover, and you'll see a row of small fuses with labels. Look for one labeled 'regulator' or 'window'—it's usually a 10A fuse. Don't forget to turn off the engine before checking. Use a fuse puller to take it out and see if it's blown—replace it if it is. A quick reminder: fuses in old cars tend to blow easily. If they frequently burn out, it might indicate a wiring short circuit or aging switches. In such cases, it's best to take the car to a repair shop to check the circuit rather than trying to fix it yourself to avoid electrical fires.
Want to DIY replace the window regulator fuse on your old Jetta? Open the fuse box cover under the dashboard on the driver's side, usually marked with locations like F20. Pull it out to check if it's blown, then replace it with a new fuse of the same amperage. Remember to turn off the power during the process, and using a test pen is safer. Related to this, if the window regulator issue persists with a good fuse, it might be a faulty motor or sticky sliding rails. Regularly lubricating the window tracks can prevent this. While DIY car repairs save money, safety comes first when dealing with electrical circuits—ask for help if unsure.
