Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface with the sunroof closed.
Disconnect the vehicle battery to avoid electrical issues during repair.

2. Inspect and Clean Drainage Tubes

Tools Required: Compressed air or a flexible cleaning rod
Remove any debris from the sunroof drainage channels using a soft cloth.
Use compressed air to blow out the drainage tubes from the sunroof towards the exit points at the bottom of the vehicle.
If necessary, gently insert a flexible cleaning rod into the tubes to clear blockages.

3. Replace Sunroof Seals

Tools Required: Trim removal tool, adhesive, utility knife
Carefully remove the old sunroof seals using the trim removal tool.
Clean the sealing surfaces on the sunroof and roof to remove old adhesive.
Cut the new seal to size and apply the adhesive as per the manufacturer's instructions.
Position the new seal properly and press down to ensure a secure fit.

4. Realign the Sunroof (if necessary)

Tools Required: Torque wrench, socket set
Inspect the sunroof's alignment and adjust it if it appears misaligned.
Loosen the mounting bolts (if applicable) and adjust the sunroof position until it is flush with the roof surface.
Retighten the bolts to the manufacturer’s specified torque settings.

5. Reconnect Battery and Test

Reconnect the vehicle battery.
Open the sunroof fully and close it to ensure proper operation.
Test the drainage system by pouring water into the sunroof channels and checking for leaks inside the vehicle.
