Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative terminal of the battery to ensure safety.

2. Inspect and Replace Fuse

Locate the fuse box (typically under the dashboard or in the engine compartment).
Remove the fuse for the power windows (check the owner’s manual for the exact fuse location).
Inspect the fuse for any breaks in the filament.
Replace the fuse if it is blown with one of the same amperage.
Reconnect the battery terminal and test the windows.

3. Replace Power Window Switch

Remove the door panel using a socket set and trim removal tools.
Disconnect the electrical connector from the power window switch.
Test the switch with a multimeter; if faulty, replace it with a new unit.
Reconnect the electrical connector and reassemble the door panel.

4. Replace Window Motor

If the switch is functional, proceed to the window motor.
Remove the door panel again for access.
Disconnect the motor connector.
Test the motor directly with a 12V battery to confirm it's faulty.
If defective, unbolt the motor from the door frame and replace it with a new motor.
Reconnect the motor and reassemble the door panel.

5. Final Assembly

Ensure all connections are secure.
Double-check that the door panel is properly aligned and all clips are reinserted.
Reconnect the negative battery terminal and test the functionality of all power windows.
