Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle in a dry area and ensure the engine is off.
Disconnect the battery to avoid any electrical issues.

2. Inspect and Clean Drainage Tubes

Remove the sunroof trim panel by gently prying it off with a trim removal tool.
Locate the drainage tubes at each corner of the sunroof.
Use a flexible cleaning brush or compressed air to clear any obstructions in the drainage tubes.
Ensure each tube is securely attached to the sunroof frame.

3. Replace Damaged Seals

Remove the existing sunroof seal by gently pulling it away from the frame.
Clean the channel where the seal was adhered using a solvent to remove any old adhesive.
Measure and cut a new sunroof seal to fit, ensuring a snug fit.
Apply weatherproof adhesive to the channel and firmly press the new seal into place.

4. Recheck Sunroof Alignment

Open the sunroof and visually inspect for any misalignment.
If misaligned, adjust the sunroof mechanism using a socket set to loosen the mounting bolts.
Once aligned, retighten the mounting bolts to the manufacturer’s torque specifications (typically around 7-9 Nm).

5. Reassemble and Test

Reinstall the sunroof trim panel by snapping it back into place.
Reconnect the battery.
Perform a water test by pouring water over the sunroof to ensure proper drainage and that no leaks occur.
