Solution

1. Preparation

Gather tools: flathead screwdriver, Phillips screwdriver, socket set, multimeter, and a trim removal tool.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Remove the Door Panel

Use a trim removal tool to gently pry off the door panel clips.
Remove any screws securing the door panel, typically located near the handle and along the bottom edge.
Carefully lift the door panel upwards to disengage it from the window frame, and disconnect any electrical connectors for switches or speakers.

3. Inspect the Window Motor and Regulator

Locate the window motor and regulator assembly.
Check for any visible damage or disconnection of wires.
Test the motor by applying direct power from the battery to see if it operates; if it does not work, proceed to replace the motor.

4. Replace the Window Motor (if necessary)

Disconnect the motor from the regulator by removing the screws holding it in place.
Remove the old motor and replace it with a new one, ensuring it is securely fastened using the screws.
Reconnect the motor wiring harness.

5. Reassemble the Door Panel

Reattach the door panel by aligning it with the door frame and pressing it back into place.
Reconnect any electrical connectors and secure the door panel with screws.
Reinstall any trim pieces that were removed.

6. Test the Window Function

Reconnect the vehicle battery and test the window operation using the switch.
Ensure the window moves smoothly up and down without any obstruction.
