Solution

1. Preparation

Gather tools: socket set, trim removal tool, multimeter.
Ensure the vehicle is parked safely and powered down.
Disconnect the 12V battery for safety.

2. Inspect and Replace Fuse

Locate the fuse box (usually under the dashboard or in the frunk).
Remove the cover and identify the power window fuse using the diagram.
Use a multimeter to check if the fuse is blown (continuity test).
If blown, replace it with a fuse of the same amperage (typically 30A).

3. Remove Door Panel

Use a trim removal tool to carefully pry off the door panel clips.
Unscrew any visible screws securing the panel (usually around the armrest and handle).
Gently lift the panel upward to detach it from the door frame; be cautious of wiring attached to the panel.

4. Inspect Window Motor and Wiring

Locate the window motor within the door assembly.
Visually inspect the motor and wiring for damage or disconnection.
If accessible, test the motor using a multimeter for proper voltage and functionality.
If the motor is faulty, remove it by unscrewing it from its mounting position.

5. Replace Window Motor (if necessary)

Disconnect the motor wiring harness.
Install the new window motor by reversing the removal steps.
Reconnect the wiring harness and secure the motor in place.

6. Reassemble Door Panel

Carefully align the door panel back onto the door frame.
Secure it by tightening screws and pressing the panel clips back into place.
Reconnect the 12V battery and test the window operation.
