Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle battery to avoid any electrical issues.
Remove any items from the vehicle that could be damaged by water.

2. Inspect and Clean Drainage Tubes

Tools Required: Compressed air or a flexible cleaning tool.
Remove the sunroof panel by releasing the clips or screws securing it.
Locate the drainage tubes; they are typically found at the corners of the sunroof frame.
Use compressed air to blow through the drainage tubes to clear any blockages.
If using a flexible cleaning tool, gently insert it into the tube to remove debris.

3. Replace Damaged Seals

Tools Required: Utility knife, adhesive sealant, or replacement seal.
Carefully remove the old seal from the sunroof frame using a utility knife.
Clean the surface where the new seal will adhere.
Apply adhesive sealant to the frame, if necessary, and press the new seal into place.
Ensure the seal is seated properly and evenly around the sunroof.

4. Test the Sunroof

Reinstall the sunroof panel and secure it with clips or screws.
Reconnect the vehicle battery.
Pour water around the sunroof area to test for leaks.
Operate the sunroof to ensure it opens and closes smoothly without obstruction.
