Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shorts.
Ensure the vehicle is parked on a level surface.

2. Inspect and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the sunroof fuse using a fuse puller.
Inspect the fuse for any signs of damage; replace it with a new fuse of the same amperage if blown.
Reinsert the fuse into the socket.

3. Test and Replace the Sunroof Switch

Remove the center console or dashboard panel to access the sunroof switch.
Disconnect the electrical connector from the switch.
Use a multimeter to test for continuity in the switch when pressed.
If defective, replace the sunroof switch with a new one.
Reconnect the switch and reassemble the console/dashboard.

4. Inspect and Replace the Sunroof Motor

Access the sunroof motor, typically located above the headliner.
Disconnect the wiring harness from the motor.
Use a multimeter to check for voltage at the motor connector when the switch is activated.
If no voltage is present, trace the wiring for breaks or shorts.
If the motor is faulty, remove it by unscrewing the retaining bolts and replace it with a new motor.

5. Clean and Align the Sunroof Track

Manually close the sunroof if possible to access the track.
Use a soft cloth and cleaning solution to remove any debris or buildup in the sunroof track.
Ensure the sunroof is aligned properly; adjust the mounting points if necessary.
Lubricate the track lightly with silicone spray.
