Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Clear Obstructions

Remove any debris from the sunroof tracks using a soft brush and cloth.
Ensure that the drainage tubes are clear; use compressed air to blow out any clogs.

3. Check and Replace the Fuse

Locate the fuse box and identify the fuse for the sunroof.
Remove the fuse and inspect for damage; replace it with a new fuse of the same amperage if necessary.
