Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent electrical shorts.
Gather necessary tools: socket set, flathead screwdriver, multimeter, and a flashlight.

2. Inspect and Clean Sunroof Track

Use a flathead screwdriver to remove any debris from the sunroof track.
Wipe down the track using a cloth with a mild cleaner to remove any old lubricant.
Apply a silicone-based lubricant to the track to ensure smooth operation.

3. Test and Replace Sunroof Motor (if needed)

Reconnect the battery and test the sunroof operation.
If it remains non-functional, remove the sunroof motor:
- Locate the motor under the headliner, typically at the rear of the sunroof assembly.
- Unscrew the mounting screws with a socket set and disconnect the wiring harness.
Install the new motor (if needed):
- Connect the wiring harness securely to the new motor.
- Position it in place and secure with screws. Torque to manufacturer's specifications (typically around 8-10 Nm).

4. Adjust Sunroof Alignment

Manually close the sunroof and ensure it is aligned properly with the roof.
If misaligned, loosen the mounting screws slightly, adjust the sunroof, and retighten screws.
