Gently pull the trim away to access the sunroof mechanism.

3. Inspect and Clean the Mechanism

Visually inspect the sunroof tracks for debris or dirt.
Use a damp cloth to clean the tracks and ensure smooth operation.
Apply a silicone-based lubricant to the tracks to reduce friction.

4. Check and Replace the Sunroof Motor (if necessary)

If the motor is not working, locate it beneath the sunroof panel.
Remove any screws or bolts securing the motor using a socket set.
Disconnect the wiring harness from the motor.
Replace the motor with a new part and reattach the wiring harness.
Secure the motor in place with screws or bolts.

5. Test the Sunroof Operation
