Solution

1. Preparation

Gather tools: socket set, multimeter, and screwdrivers.
Disconnect the vehicle battery to avoid electrical shorts.

2. Inspect and Replace Fuses

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the cover and identify the power window fuse using the diagram on the cover.
Use a fuse puller or pliers to remove the fuse and check for continuity.
- If blown, replace with a fuse of the same amperage.

3. Test and Repair Wiring

Reconnect the battery temporarily and check the voltage at the window switch using a multimeter.
If voltage is present, proceed to inspect the wiring harness for fraying or disconnections.
Repair or replace any damaged wiring as needed.

4. Remove and Test Window Motor

If the wiring is intact, remove the door panel using screwdrivers and trim tools.
Disconnect the power window motor from its connector.
Use a multimeter to apply direct voltage to the motor terminals to see if it operates.
- If it works, the issue may lie with the switch or wiring.
- If it does not work, replace the window motor.

5. Reassemble Door Panel

Reattach the door panel carefully, ensuring all clips and screws are secured.
Reconnect the battery and test the power windows for functionality.
