Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and powered off.
Disconnect the 12V battery to avoid any electrical hazards.

2. Inspect and Replace the Window Switch

Tools Required: Screwdriver set, trim removal tool
Locate the window switch panel on the passenger door.
Use a trim removal tool to gently pry off the switch panel.
Disconnect the electrical connector from the back of the switch.
Test the switch using a multimeter for continuity; if faulty, replace it with a new switch.
Reconnect the new switch and reassemble the switch panel.

3. Check and Replace the Window Motor

Tools Required: Socket set, multimeter
Remove the door panel by unscrewing the fasteners and gently prying off any clips.
Disconnect the electrical connector from the window motor.
Use a multimeter to test for voltage at the motor connector while pressing the switch; if there’s no voltage, the issue may lie upstream.
If voltage is present but the motor does not operate, remove the motor by unscrewing it and replace it with a new motor.
Reconnect the new motor and reassemble the door panel.

4. Inspect Wiring and Connections

Tools Required: Wire stripper/crimper, electrical tape
Check the wiring harness leading to the window motor for any frayed or damaged wires.
Repair any damaged wires using a wire stripper and crimper, ensuring proper insulation with electrical tape.
Recheck all connections to ensure they are secure.
