Solution

1. Preparation

Gather necessary tools: flathead screwdriver, Phillips screwdriver, multimeter, socket set, and a trim removal tool.
Disconnect the vehicle battery to prevent any electrical shorts during repair.

2. Check and Replace Fuse

Locate the sunroof fuse in the vehicle’s fuse box (refer to owner's manual for exact location).
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity using a multimeter; replace with the same rating if defective.

3. Inspect and Replace Sunroof Switch

Remove the sunroof switch panel using a trim removal tool.
Disconnect the electrical connector from the switch.
Test the switch with a multimeter for continuity; replace if defective.
Reconnect the new switch and snap the panel back into place.

4. Examine and Clean Sunroof Tracks

Open the sunroof partially (if possible).
Clean the sunroof tracks thoroughly using a soft brush and a damp cloth to remove debris.
Lubricate the tracks with silicone spray to ensure smooth operation.

5. Test and Replace Sunroof Motor (if necessary)

Access the sunroof motor by removing the headliner (follow manufacturer's instructions).
Disconnect the motor's electrical connector.
Using a multimeter, check for power at the motor connector while operating the sunroof switch.
If no power is detected, the switch or wiring may need further investigation.
If power is present and the motor does not operate, replace the sunroof motor.
