Solution

1. Preparation

Gather tools and parts as listed below.
Disconnect the negative terminal of the battery to prevent any electrical shorts.

2. Inspect and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Remove the appropriate fuse for the power windows (refer to the owner’s manual).
Inspect the fuse for continuity; replace it if it is blown.
Reconnect the battery and test the window operation.

3. Examine and Test Window Switches

If the fuse is intact, check the window lock switch for proper function.
Remove the switch panel from the driver’s side door.
Use a multimeter to test for continuity on each switch.
Replace any faulty switches with new ones.

4. Check Window Motor and Wiring

If switches are operational, proceed to remove the door panel.
Disconnect the wiring harness from the window motor.
Measure the voltage at the motor harness while activating the switch.
If there is no voltage, trace the wiring back to the switch for breaks or shorts.
If there is voltage but the motor does not operate, replace the window motor.

5. Reassemble and Test

Reattach the door panel, ensuring all clips and screws are secure.
Reconnect the battery and perform a final test of all power windows.
