Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a level surface.
Disconnect the battery for safety if electrical components are involved.

2. Inspect and Clean Drainage Tubes

Tools Required: Soft-bristle brush, compressed air, or a flexible wire.
Inspect the drainage tubes located at each corner of the sunroof.
Use a soft-bristle brush to clean out any debris or dirt from the drainage openings.
Use compressed air or a flexible wire to ensure the tubes are clear and unobstructed.

3. Replace Sunroof Seals

Tools Required: Flathead screwdriver, adhesive sealant (if necessary).
Use a flathead screwdriver to carefully pry off the old sunroof seals if they appear cracked or worn.
Clean the surface thoroughly to remove any residue from the old seal.
Apply the new seal, ensuring it adheres properly and forms a complete seal.

4. Test Drainage Functionality

Pour a small amount of water into the sunroof channels and observe if it drains through the tubes.
Confirm that water exits under the vehicle and not inside the cabin.

5. Reassemble and Final Checks

Reinstall any components removed during the process, ensuring everything is secure.
Reconnect the battery if it was disconnected.
Close the sunroof and check for proper sealing and operation.
