Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface.
Disconnect the vehicle's battery to avoid electrical issues.

2. Inspect and Clean Drainage Channels

Locate the drainage holes at the corners of the sunroof.
Use a soft brush or compressed air to clear any debris or blockages in the drainage channels.
Pour water into the sunroof area to test if it drains properly.

3. Replace Sunroof Seals

Carefully remove the old seals using a trim removal tool.
Clean the surface where the new seal will be applied.
Apply the new seal, ensuring it is seated properly and evenly along the entire edge.
Use a sealant if recommended by the manufacturer.

4. Test Sunroof Functionality

Reconnect the battery.
Operate the sunroof to check for proper opening and closing.
Verify that no water leaks occur during the operation.

5. Final Inspection

Once repairs are complete, conduct a final check for any visible leaks.
Test the drainage by pouring water over the sunroof and ensuring it flows out the drainage channels without pooling.
