Solution

1. Preparation

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

2. Check and Replace Fuse

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse and inspect for any breaks in the filament.
If blown, replace with a fuse of the same amperage rating.

3. Inspect and Repair Wiring

Tools Required: Wire stripper/crimper, electrical tape
Remove the door panel to access the wiring harness.
Visually inspect the wiring for frays, breaks, or disconnections.
Repair any damaged wiring using a wire stripper and crimper, ensuring connections are secure and insulated with electrical tape.

4. Replace Power Window Switch (if necessary)

Tools Required: Screwdriver set, Torx bits (if applicable)
If the switch tested non-functional, remove the switch panel from the door.
Disconnect the wiring harness from the switch.
Install the new switch by connecting the wiring harness and securing it back into place.

5. Test Window Motor

Tools Required: Jumper wires
Disconnect the window motor from the wiring harness.
Connect jumper wires directly to the motor terminals and apply battery voltage to see if the motor operates.
If the motor runs, the issue is likely with the switch or wiring. If it doesn’t, replace the window motor.
