Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the power window fuse in the fuse box (refer to the owner's manual for exact location).
Remove the fuse using a fuse puller.
Inspect the fuse for continuity; replace it with an identical fuse rated for the same amperage if blown.

3. Test and Replace Window Switch

Remove the door panel using a trim removal tool, taking care not to damage any clips.
Disconnect the wiring harness from the window switch.
Use a multimeter to test the switch: connect leads to the switch terminals and press the switch to check for continuity.
If the switch is faulty, replace with a new switch.

4. Inspect Wiring and Connectors

While the door panel is removed, visually inspect the wiring harness and connectors for any signs of wear, fraying, or corrosion.
Repair or replace damaged wires and connectors as necessary.

5. Test Window Motor

If the switch and wiring are functional, test the window motor.
Disconnect the motor from the window regulator.
Apply direct battery power to the motor leads, ensuring proper polarity, to see if it operates.
If the motor does not function, replace it with a new motor.

6. Reassemble Components

Reattach all connectors and wiring harnesses securely.
Reinstall the door panel, ensuring all clips are seated correctly.
Reconnect the vehicle battery.
