Solution

1. Preparation

Gather necessary tools and parts before starting the repair.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to avoid electrical shock.

2. Inspect and Replace Fuses

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.
Check the fuse for continuity; if blown, replace it with a fuse of the same amperage (usually 30A).
Reconnect the battery and test the window operation.

3. Test and Replace Window Switches

Remove the door panel using a trim removal tool to access the window switches.
Disconnect the wiring harness from the switch.
Use a multimeter to check for continuity across the switch terminals when pressed.
If faulty, replace the window switch with a new unit and reassemble the door panel.

4. Inspect and Repair Wiring

Examine the wiring harness leading to the window motor and switches for any frays or breaks.
Repair any damaged wires using electrical tape or heat-shrink tubing.
Ensure all connections are secure and free from corrosion.

5. Test and Replace Window Motor

If the switches are operational, locate the window motor within the door panel.
Disconnect the motor's wiring harness.
Use a multimeter to check for voltage at the motor when the switch is activated.
If no voltage is detected, further investigate the wiring or switch.
If the motor is faulty, remove the old motor by unscrewing mounting bolts and replace it with a new motor.
