Solution

1. Preparation

Gather tools: socket set, multimeter, flathead screwdriver, Phillips screwdriver.
Disconnect the battery to prevent electrical shock.

2. Check and Replace the Fuse

Locate the fuse box; typically found under the dashboard or in the engine bay.
Remove the power window fuse using a fuse puller or pliers.
Inspect the fuse for any signs of damage (burnt or broken filament).
Replace with a new fuse of the same amperage if necessary.

3. Inspect and Repair the Switches

Use a screwdriver to remove the switch panel from the driver's side door.
Disconnect the wiring harness from the switch.
Test the switch with a multimeter to ensure it operates correctly.
If faulty, replace the switch with a new one and reconnect the harness.

4. Test Window Motors

Access the individual window motor by removing the door panel.
Disconnect the motor's electrical connector.
Using a multimeter, check for voltage at the motor connector while operating the switch.
If no voltage is present, trace the wires back to the master switch.
If voltage is present and the motor does not operate, replace the window motor.

5. Reassemble Components

Reinstall the door panel, ensuring all clips and screws are secure.
Reconnect the battery.
