Solution

1. Preparation

Tools Required:
- Flathead screwdriver
- Torx screwdriver set
- Multimeter
- OBD-II scanner
Disconnect the vehicle’s battery to ensure safety while working on electrical components.

2. Inspect and Clean Sunroof Components

Remove the sunroof switch from the overhead console using a flathead screwdriver.
Clean the contacts of the switch with electronic cleaner to remove any corrosion.
Inspect the sunroof tracks for dirt or debris; clean with a soft cloth and a suitable lubricant.

3. Check and Replace Fuses

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the sunroof fuse (refer to the owner's manual for the exact location).
Remove the fuse and inspect it visually; replace if blown with the same amperage rating.

4. Test the Sunroof Motor

Locate the sunroof motor, which is typically accessed by removing the headliner.
Use a multimeter to check for voltage at the motor connector when the switch is activated.
If no voltage is present, further investigate wiring or switch issues.
If voltage is present but the motor does not operate, replace the sunroof motor.

5. Manual Closure (if necessary)

If the above steps do not resolve the issue and the sunroof needs to be closed immediately, locate the manual close feature (usually a small slot or access point near the motor).
Use a Torx screwdriver to turn the manual close mechanism until the sunroof is securely shut.
