Solution

1. Preparation

Gather necessary tools and materials.
Disconnect the negative terminal of the battery to ensure safety while working on electrical systems.

2. Inspect and Replace the Fuse

Tools Required: Fuse puller or pliers
Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the power window fuse based on the diagram on the fuse box cover.
Remove the fuse and inspect it. If the metal strip is broken, replace it with a new fuse of the same amperage.

3. Replace the Power Window Switch (if faulty)

Tools Required: Screwdriver set, trim removal tool
Remove the door panel using the trim removal tool to access the switch.
Disconnect the wiring harness from the switch.
Replace the faulty switch with a new one and reconnect the harness.
Reattach the door panel securely.

4. Check and Replace Power Window Motor (if necessary)

Tools Required: Socket set, multimeter
If the power window switch is functional, proceed to the power window motor.
Remove the door panel to access the motor.
Disconnect the motor's wiring harness and test for voltage while operating the switch.
If no voltage is detected, further investigate the wiring. If voltage is present, replace the motor.
To replace, remove the motor from its mounting, install the new motor, and reconnect the wiring.
