Solution

1. Preparation

Gather tools including a flathead screwdriver, multimeter, and socket set.
Disconnect the battery to prevent electrical shock.

2. Inspect and Replace the Sunroof Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Use the fuse puller to remove the sunroof fuse (refer to the owner's manual for the exact location).
Inspect the fuse; if it appears blown (broken wire inside), replace it with a new fuse of the same amperage.
Reconnect the battery.

3. Check the Sunroof Motor and Track

Remove the interior trim panel surrounding the sunroof (use a flathead screwdriver to gently pry it off).
Locate the sunroof motor; it is usually found near the rear of the sunroof assembly.
Use a multimeter to check for power at the motor connector. If power is present but the motor is not functioning, replace the motor.
Inspect the sunroof track for debris; clean any obstructions using a soft cloth.
Apply a small amount of silicone lubricant to the track to ensure smooth operation.

4. Test the Sunroof Operation

Reconnect the battery.
Test the sunroof switch to close the sunroof.
If the sunroof operates properly, reassemble the interior trim panel.
