Solution

1. Preparation

Tools Required: Screwdriver set, multimeter, OBD-II scanner, flashlight, compressed air.
Gather necessary tools and ensure the vehicle is parked on a level surface with the ignition off.

2. Inspect the Sunroof Switch

Remove the switch panel using a flathead screwdriver or trim removal tool.
Disconnect the switch connector and inspect for corrosion or damage.
Use a multimeter to test for continuity when the switch is activated.

3. Check the Fuse

Locate the fuse box and identify the fuse for the sunroof (refer to the owner’s manual for exact location).
Remove the fuse and inspect it visually; replace it if it is blown.
If necessary, test the fuse with a multimeter to confirm functionality.

4. Test the Sunroof Motor

Remove the sunroof motor cover (if applicable) to access the motor.
Disconnect the motor connector and use a multimeter to check for voltage at the connector while operating the switch.
If there is voltage but the motor does not operate, replace the motor. If no voltage is present, trace wiring back to the switch.

5. Inspect the Sunroof Tracks

Open the sunroof manually (if possible) and clean the tracks with a soft cloth.
Inspect for any obstructions such as dirt or debris. Use compressed air to clear any blockages.

6. Check the Drain Tubes

Inspect the sunroof drain tubes located at the corners of the sunroof opening.
Use compressed air to blow through the tubes and ensure they are not clogged, allowing proper drainage.
