Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Disconnect the battery to prevent electrical shocks.

2. Replace Blown Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the fuse for the power windows using a fuse puller or needle-nose pliers.
Replace it with a new fuse of the same amperage (usually 30A for power windows).

3. Repair or Replace Window Switch

Remove the panel surrounding the window switch using a trim removal tool.
Disconnect the wiring harness from the switch.
Test the switch with a multimeter for continuity; if faulty, replace it with a new switch.
Reconnect the new switch and reassemble the panel.

4. Inspect Wiring and Connections

Check the wiring harness for any frayed or broken wires.
Repair any damaged wires using solder or appropriate connectors.
Ensure all connections are secure and free of corrosion.

5. Replace Window Motor (if necessary)

Remove the door panel to access the window motor (remove screws and clips).
Disconnect the motor from the wiring harness.
Unscrew the motor from its mounting and replace it with a new motor.
Reassemble the door panel and test the window operation.
