Solution

1. Preparation

Gather tools: socket set, multimeter, flathead screwdriver, torx screwdriver, and a trim removal tool.
Disconnect the negative battery terminal to ensure safety during the repair.

2. Remove the Door Panel

Use a trim removal tool to carefully pry off the door panel clips.
Remove any screws securing the door panel (often located near the handle and at the bottom).
Gently lift the door panel upwards to disconnect it from the door, being cautious of any wiring attached to the panel.

3. Inspect and Test the Window Motor

Locate the window motor and disconnect the wiring harness.
Using a multimeter, test the motor for continuity. If there is no continuity, the motor should be replaced.
If the motor is operational, check the window regulator for binding or damage.

4. Replace the Window Motor (if necessary)

If the motor is faulty, remove the mounting screws securing the motor to the regulator.
Carefully detach the motor from the regulator and install the new motor by reversing the removal steps.
Ensure the motor is properly aligned and secured before reattaching the wiring harness.

5. Reassemble the Door Panel

Reattach the door panel by aligning it with the clips and pressing down firmly.
Reinsert and tighten the screws removed earlier.
Reconnect the negative battery terminal.
