Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the ignition is turned off for safety.
Disconnect the battery to prevent electrical shock.

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine bay.
Remove the cover and identify the power window fuse (refer to the diagram on the cover).
Use a multimeter to check continuity of the fuse.
If blown, replace it with a new fuse of the same amperage (usually 30A for power windows).

3. Test Window Switches

Remove the door panel using a trim tool to access the window switch.
Disconnect the window switch connector and test for voltage using a multimeter.
If no voltage is present, replace the switch with a new one.

4. Inspect Window Motor

If the switch is functional, check the window motor.
Remove the door panel and access the window motor.
Disconnect the motor connector and test for voltage when the switch is pressed.
If no voltage is detected, further investigate the wiring or replace the motor if necessary.

5. Reassemble and Test

Reattach the door panel securely, ensuring all clips and screws are in place.
Reconnect the battery.
Test the power windows to ensure they operate correctly.
