Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the ignition off.
Disconnect the vehicle's battery to avoid any electrical shorts.

2. Remove the Door Panel

Use a trim removal tool to carefully pry off the door panel clips.
Remove the screws securing the door panel (typically located in the armrest and near the handle).
Carefully detach the door panel from the door, taking care not to damage any clips or wiring.

3. Inspect and Test Wiring

Visually inspect the wiring harness connected to the window motor for any signs of damage or disconnection.
Use a multimeter to check for continuity in the wires leading to the window motor.
If continuity is absent, trace the wiring back to the control switch and inspect for damage.

4. Test and Replace Window Motor (if necessary)

Disconnect the window motor connector.
Use a multimeter to test the motor for resistance. If resistance is infinite, the motor is defective.
If defective, replace the window motor with a new one.
Connect the new motor and secure it to the window assembly.

5. Reassemble Door Panel

Reattach the door panel by aligning it with the clips and ensuring it fits securely.
Replace screws to secure the panel.
Reconnect the battery and test the window operation before finalizing assembly.
