Solution

1. Preparation

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

2. Inspect and Clean the Sunroof Track

Remove any debris or obstructions from the sunroof track using a soft brush.
Clean the track with a damp cloth to remove dirt and grime.

3. Check and Replace the Fuse

Locate the sunroof fuse in the fuse box (consult the owner's manual for the exact location).
Remove the fuse using a fuse puller.
Inspect the fuse for continuity and replace it with a new fuse of the same amperage if blown.

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

Reconnect the battery and test the sunroof switch again.
If the motor does not operate, remove the sunroof motor from its mounting.
- Tools: Socket set, Torx screwdriver
Disconnect the wiring harness from the motor.
Use a multimeter to test for voltage at the motor connector while operating the switch.
If there is no voltage, check wiring continuity; if voltage is present but the motor does not operate, replace the motor.
- Install a new sunroof motor by reversing the removal steps.

5. Reassemble and Test

Reattach any panels or components removed during the repair.
Reconnect the battery and test the sunroof operation to ensure it closes properly.
