Solution

1. Preparation

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

2. Inspect and Clean the Sunroof Switch

Remove the overhead console using a trim tool.
Disconnect the sunroof switch connector.
Clean the switch terminals with electrical contact cleaner.
Reconnect the switch and re-test operation.

3. Check and Replace the Fuse

Locate the fuse box (usually under the dashboard or hood).
Identify the fuse associated with the sunroof (refer to the vehicle's manual).
Remove the fuse and inspect it for continuity using a multimeter.
If blown, replace it with a fuse of the same amperage (typically 10A).

4. Test the Sunroof Motor

Access the sunroof motor, usually located above the headliner.
Disconnect the motor's wiring harness.
Use a multimeter to check for power at the connector when the sunroof switch is activated.
If power is present but the motor does not operate, replace the motor.

5. Inspect the Sunroof Mechanism

Remove the sunroof panel by unscrewing the retaining screws around the perimeter.
Clean the tracks and ensure there are no obstructions.
Lubricate the tracks with a silicone-based lubricant.
Reinstall the sunroof panel and secure it.
