Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Remove the power window fuse using a fuse puller.
Inspect the fuse for continuity; replace it if blown with a fuse of the same amperage.

3. Replace or Repair Window Switch

Remove the trim panel surrounding the window switch using a trim removal tool.
Unscrew and disconnect the switch from the wiring harness.
Test the switch with a multimeter; replace if defective.
Reinstall the new or repaired switch by reversing the removal steps.

4. Inspect and Replace Window Motor

Remove the door panel using a socket set and a trim removal tool.
Disconnect the window motor from the wiring harness.
Test the motor directly with a power source to see if it operates.
If the motor is faulty, replace it by removing the bolts and wiring, then install the new motor and reassemble the door panel.

5. Replace Window Regulator (if necessary)

If the window motor is functional but the window does not move, the regulator may need replacement.
Remove the window glass if it's not already loose by detaching it from the regulator clips.
Unscrew the regulator from the door frame and disconnect it from the motor.
Install the new regulator by reversing the steps, ensuring all connections are secure.
