2. Inspect and Clean Drainage System

Locate Drainage Tubes: Identify the sunroof drainage tubes, typically located at the corners of the sunroof frame.
Clear Blockages: Use compressed air or a small wire to carefully clear any debris or blockages in the drainage tubes.
Test Drainage: Pour a small amount of water into the sunroof channel and ensure it drains through the tubes without issue.

3. Repair Sunroof Seal

Inspect Seal: Carefully examine the rubber sunroof seal for cracks or wear.
Apply Sealant: If the seal is damaged but not completely broken, apply silicone sealant along the affected area and smooth it out.
Replace Seal: If the seal is extensively damaged, remove the old seal and replace it with a new one by peeling off the old seal and adhering the new seal into place.

4. Reassemble and Test

Reinstall any Removed Components: If any interior panels or trim pieces were removed, carefully reinstall them.
Reconnect Battery: Reconnect the vehicle battery.
Test Sunroof Operation: Open and close the sunroof to ensure proper functionality.
