Solution

1. Preparation

Gather tools and parts needed for the repair.
Tools Required:
- Multimeter
- Fuse puller or pliers
- Screwdrivers (flathead and Phillips)
- Socket set
- Torque wrench

2. Check and Replace Fuses

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Use a fuse puller to remove the power window fuse (check the owner’s manual for the specific fuse location).
Inspect the fuse for continuity; replace if blown with a new fuse of the same amperage.

3. Inspect and Repair Wiring Harness

Remove the door panel using a screwdriver and/or socket set to access the wiring harness.
Inspect the wiring for any signs of wear, fraying, or corrosion.
Repair or replace damaged wires as necessary, ensuring connections are secure.

4. Replace Power Window Switch

If the switch is faulty, remove it from the door panel by gently prying it out.
Disconnect the wiring harness from the switch.
Connect the new switch and reinsert it into the door panel.

5. Test Window Motors

Remove the window motor from the door by loosening the mounting bolts.
Connect the motor directly to the vehicle battery using jumper wires to test functionality.
If the motor does not operate, replace it with a new one.
