Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Fuse

Locate the fuse box according to the owner’s manual.
Remove the power window fuse using a fuse puller.
Inspect the fuse; if blown, replace it with a fuse of the same amperage (typically 30A).
Reinstall the fuse and reconnect the battery.

3. Inspect and Replace Window Switch

Remove the door panel using a trim removal tool.
Disconnect the window switch connector.
Test the switch with a multimeter for continuity.
If faulty, replace with a new switch and reconnect.

4. Test and Replace Window Motor

If the switch is working, remove the motor from the door panel.
Apply direct battery power to the motor terminals to check functionality.
If the motor does not operate, replace it with a new window motor.
Reinstall the motor and reconnect the harness.

5. Check Wiring Harness

Inspect the wiring harness connected to the window switch and motor.
Look for signs of fraying, corrosion, or disconnections.
Repair or replace damaged sections as necessary.
