Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Window Switch

Remove the trim panel around the window switch using a trim removal tool.
Disconnect the electrical connector from the switch.
Inspect the switch for continuity using a multimeter. If faulty, replace with a new switch.
Reconnect the new switch and test its operation before reassembling the trim.

3. Check and Replace Fuses

Locate the fuse box and identify the fuse for the power windows using the owner's manual.
Remove the fuse and inspect it for continuity; replace with a new fuse of the same amperage if blown.
Reinstall the fuse and check for window operation.

4. Test and Replace Window Motor

Remove the door panel by unscrewing any fasteners and using a trim tool to detach clips.
Locate the window motor and disconnect the electrical connector.
Use a multimeter to check for voltage at the motor connector while pressing the window switch.
If no voltage is present, trace wiring back to the switch. If voltage is present but the motor does not operate, replace the window motor.
Install the new motor and reassemble the door panel.

5. Inspect and Repair Window Regulator

After removing the door panel, visually inspect the window regulator for damage or misalignment.
If damaged, remove the window regulator by unscrewing it from the door frame.
Install a new window regulator and ensure it is properly aligned.
Reconnect the window motor and test the system before reinstalling the door panel.
