Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety.
Allow time for any components to cool if previously in use.

2. Check and Replace Fuse

Locate the fuse box; refer to the owner’s manual for the specific location of the power window fuse.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace if blown (usually with a 15A fuse for windows).
Reinstall the fuse and reconnect the battery.

3. Inspect and Replace Window Switch

Remove the door panel using a socket set and trim removal tools.
Disconnect the window switch connector and test with a multimeter for continuity.
If faulty, replace the window switch with a new one.
Reconnect the switch and secure the door panel back in place.

4. Test Window Motor

If the window switch is functional, check the window motor.
Disconnect the motor connector and test voltage while pressing the switch.
If no voltage is present, trace back to the switch or wiring.
If voltage is present but the motor doesn’t operate, replace the motor.

5. Reassemble

Once repairs are completed, reattach the door panel securely.
Ensure all clips and screws are replaced.
Reconnect the battery and test window operation.
