Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shorts.
Ensure the vehicle is parked on a flat surface and in a safe environment.

2. Inspect and Replace the Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the sunroof fuse using the owner's manual.
Remove the fuse using a fuse puller or pliers.
Inspect for any signs of damage; if blown, replace with a new fuse of the same amperage.

3. Test the Sunroof Motor

Reconnect the battery and locate the sunroof motor, usually found in the headliner area above the sunroof.
Use a multimeter to test the motor's voltage supply by connecting leads to the motor terminals while operating the switch.
If there is no voltage, check wiring for continuity; repair or replace as needed.

4. Check and Clear Obstructions

Manually inspect the sunroof tracks and surrounding areas for debris or blockages.
Use a soft brush or vacuum to clean the tracks and ensure smooth operation.
If misalignment is present, adjust the sunroof frame as per manufacturer specifications.

5. Reassemble and Test

Reinstall the headliner and any removed interior components.
Reconnect the battery.
Test the sunroof operation using the switch to ensure it opens and closes smoothly.
