Solution

1. Preparation

Gather tools: flathead screwdriver, socket set, multimeter, and a replacement fuse if necessary.
Ensure the vehicle is in park and the ignition is turned off.
Disconnect the battery to avoid electrical shock.

2. Inspect and Replace Fuse

Locate the fuse box; usually found under the dashboard or in the engine compartment.
Remove the cover and identify the power window fuse using the diagram on the cover.
Inspect the fuse visually; if the metal strip is broken, replace it with a new fuse of the same amperage.
Reconnect the battery.

3. Test Power Window Switch

Remove the switch panel using a flathead screwdriver to carefully pry it up.
Disconnect the electrical connector from the back of the switch.
Use a multimeter to check for continuity in the switch. If there's no continuity, replace the switch.

4. Check Window Motor and Wiring

If the switch is functioning, locate the window motor in the door panel.
Disconnect the motor's electrical connector and use the multimeter to check for voltage when the switch is pressed.
If voltage is present but the motor does not operate, replace the window motor.
If no voltage is detected, trace the wiring back to the switch or fuse box for damage.

5. Reassemble Interior Door Panel

If any parts were removed to access the window motor, reassemble the interior door panel carefully.
Ensure all clips and screws are securely fastened.
