Solution

1. Preparation

Gather tools and ensure the vehicle is parked on a level surface.
Disconnect the battery to prevent electrical issues.

2. Inspect and Clean the Sunroof Seal

Remove any debris and dirt from the sunroof seal using a soft cloth and cleaning solution.
Inspect the seal for any cracks or wear. If found, the seal will need to be replaced.

3. Clear Drainage Channels

Tools Required: Compressed air or a flexible wire
Locate the drainage channels around the sunroof. Use compressed air or a flexible wire to carefully clear any blockages in the drainage tubes.
Ensure that the tubes are free-flowing to allow water to drain properly.

4. Check Drainage Tube Connection

Inspect the connection points of the drainage tubes at the sunroof and underneath the vehicle.
Ensure the tubes are securely attached and not pinched. Reattach or replace tubes as necessary.

Remove the old seal carefully. Clean the surface where the new seal will be applied.
