Solution

1. Preparation

Tools Required: Screwdriver set, trim removal tool, multimeter, socket set, OBD-II scanner.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Remove the Door Panel

Use a trim removal tool to carefully detach the door panel clips.
Remove all screws securing the door panel, typically located near the handle and bottom edge.
Gently lift the door panel upwards and disconnect any wiring harnesses attached to switches or speakers.

3. Inspect and Test the Window Motor

Locate the window motor and check for any visible damage or disconnections.
Connect the multimeter to the motor terminals while activating the window switch. Verify that it receives the correct voltage (usually around 12V).
If there is no voltage, trace the wiring back to the switch and check for any breaks or shorts.

4. Replace the Window Motor (if necessary)

If the motor is defective, remove the motor by unscrewing it from the regulator.
Install the new motor in the reverse order, ensuring it is securely fastened.
Reconnect all wiring harnesses and ensure there are no obstructions in the window's path.

5. Reassemble the Door Panel

Carefully reattach the door panel, ensuring all clips and screws are secured.
Reconnect any wiring harnesses that were disconnected.
Reconnect the vehicle battery.
