Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace the Fuse

Locate the fuse box (often under the dashboard or in the engine bay).
Identify the fuse labeled for the sunroof using the fuse diagram.
Remove the fuse and inspect it; replace it if it is blown.
Reconnect the battery and test the sunroof operation.

3. Test and Replace the Sunroof Switch

Remove the sunroof switch from the vehicle's console.
Using a multimeter, test for continuity across the switch terminals.
If faulty, replace the switch with a new one and reinstall it.

4. Access and Inspect the Sunroof Motor

Remove the headliner carefully to access the sunroof motor.
Disconnect the motor from the wiring harness.
Use a multimeter to check for power at the motor connector when the switch is activated.
If there is power and the motor does not run, replace the motor.

5. Clear the Sunroof Track

If the sunroof is mechanically stuck, inspect the track.
Use a soft brush or compressed air to remove any debris.
Apply a silicone-based lubricant to the sunroof tracks to ensure smooth operation.
