Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the power window fuse using a fuse puller or pliers.
Inspect the fuse for any signs of damage; replace with a new fuse of the same amperage if necessary.

3. Repair or Replace the Window Switch

Remove the door panel using a trim removal tool to access the window switch.
Disconnect the switch connector and test for continuity.
If defective, replace with a new switch and reconnect the harness.
Reinstall the door panel securely.

4. Inspect and Repair Wiring

Trace the wiring from the switch to the motor for any signs of wear or damage.
Repair any damaged wires using solder and heat-shrink tubing or replace the entire harness if necessary.

5. Test the Power Window Motor

If the motor is suspected to be faulty, remove it from the door panel.
Connect the motor directly to a 12V power source to test its operation.
If the motor does not operate, replace it with a new power window motor.

6. Reassemble and Test

Reinstall the door panel and secure all clips and screws.
Reconnect the battery and test the power windows for proper operation.
