To find the relevant fuse(s):
1. Consult your owner's manual: This is the best place to start. It will have a diagram showing the fuse box locations (there's usually one under the hood and one inside the cabin, often under the dash) and which fuse(s) control the power windows. Look for fuses related to "power windows," "accessories," or "power."
2. Check both fuse boxes: Carefully inspect the fuses in both boxes. Look for a blown fuse (a broken filament inside the glass). If you find one, replace it with a fuse of the *same amperage*.
If the fuses are fine:
The problem is almost certainly *not* a fuse. The likely culprits are:
* Passenger window switch: The switch itself might be faulty. Try testing the other window switches to see if they work. If the other window switches are functioning, it points more to the passenger side switch being bad.
* Passenger window motor: The motor in the door might have burned out or become jammed.
* Wiring harness: A wire in the harness leading to the door could be broken or disconnected. This is often damaged from repeated use of the door.
Troubleshooting Steps:
* Test the other windows: If the other windows work, the problem is likely isolated to the passenger side.
* Check the switch: See if the passenger window switch feels different than the others. A weak click or no click suggests it's bad.
* Listen at the door: When you try to raise the window, listen carefully at the passenger side door. You might hear a grinding noise indicating a problem with the motor or a mechanical issue within the door.
You will likely need a multimeter to test the switch and wiring if you want to diagnose it further. Otherwise, it's recommended to take it to a mechanic or auto electrician. Replacing the switch, motor, or repairing the wiring usually involves removing the door panel which isn't particularly easy for the average person.
