Solution

1. Preparation

Gather tools: flathead screwdriver, Phillips screwdriver, multimeter, and replacement fuse if needed.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Clean the Sunroof Tracks

Remove any debris from the sunroof tracks using a soft brush or cloth.
Inspect the tracks for any signs of damage or corrosion.
Clean the tracks with a mild automotive cleaner and ensure they are free of obstructions.

3. Check the Sunroof Switch

Remove the sunroof switch panel using a flathead screwdriver to gently pry it off.
Inspect the wiring harness for any loose connections or damage.
If necessary, replace the switch with a new one by disconnecting the old switch and connecting the new one.

4. Test the Sunroof Motor

Locate the sunroof motor, usually situated above the headliner near the sunroof assembly.
Disconnect the motor's wiring harness.
Using a multimeter, check for voltage at the motor connector while attempting to operate the sunroof. If voltage is present but the motor does not operate, replace the motor.

5. Replace the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse related to the sunroof (refer to the owner's manual for the specific fuse location).
Remove the fuse and check for continuity using a multimeter. If blown, replace it with a new fuse of the same amperage.

6. Reassemble Components

Reattach the sunroof switch panel and ensure it is secured properly.
Reconnect the vehicle battery.
