Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the vehicle battery to avoid any electrical issues.
Park the vehicle in a dry area to minimize further water intrusion.

2. Inspect and Replace Seals

Tools Required: Flathead screwdriver, silicone sealant, utility knife.
Inspect the sunroof seal thoroughly.
If damaged, carefully pry off the old seal using a flathead screwdriver.
Clean the area where the seal was located to remove any old adhesive.
Measure and cut the new seal to size, ensuring it fits snugly.
Apply silicone sealant to the area and press the new seal into place.
Allow the sealant to cure as per manufacturer instructions.

3. Clear Drainage Tubes

Tools Required: Compressed air or a flexible cleaning tool.
Locate the drainage tubes, typically found in the corners of the sunroof assembly.
Use compressed air to blow out any blockages in the tubes.
Alternatively, use a flexible cleaning tool to clear any debris that may be clogging the drainage path.
Test by pouring water into the sunroof and ensuring it drains freely outside the vehicle.

4. Realign Sunroof

Tools Required: Socket set, torque wrench.
If the sunroof is misaligned, loosen the mounting bolts using a socket set.
Adjust the position of the sunroof until it sits flush with the roofline.
Tighten the bolts to the manufacturer’s specified torque value.
Test the operation of the sunroof to ensure it opens and closes smoothly.
