Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle battery to avoid any electrical issues.
Ensure the vehicle is parked on a level surface.

Tools Required:

Screwdriver set
Pliers
Shop towels
Water hose
Vacuum with wet/dry capability (optional)

2. Inspect and Clean Drains

Locate the sunroof drain holes, typically found in the corners of the sunroof opening.
Use a small flexible wire or compressed air to clear any blockages in the drain tubes.
If necessary, use a wet/dry vacuum to remove any accumulated debris from the drainage system.

3. Replace Sunroof Seals

Remove any trim pieces around the sunroof if necessary to access the seals.
Carefully pull out the old seals from the sunroof frame.
Clean the surface where the new seals will be applied to ensure proper adhesion.
Install new sunroof seals, ensuring they fit snugly and evenly along the frame.

4. Check and Align Sunroof

Open the sunroof and check if it is aligned properly.
If misaligned, adjust the sunroof mechanism by loosening the mounting screws and repositioning it.
Tighten the screws to the manufacturer’s torque specifications (consult repair manual for exact torque values).

5. Conduct Water Test

Once repairs are complete, conduct a water test by pouring water over the sunroof.
Observe if any leaks occur inside the vehicle, ensuring all areas are sealed properly.
