1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Drainage Channels

Open the sunroof fully.
Use a soft brush or cloth to clean any debris from the drainage channels around the sunroof.
Ensure all channels are free of dirt, leaves, and other obstructions.

Locate the drainage tubes at each corner of the sunroof.
Use compressed air to blow through each tube, ensuring they are clear of clogs.
If debris is found, gently pull it out using a flexible wire or vacuum.

4. Replace Damaged Seals

If the seals are damaged, carefully remove them from the sunroof frame.
Clean the contact area with isopropyl alcohol.
Apply new automotive-grade sealant or adhesive around the frame and press the new seal into place.
Allow the sealant to cure as per the manufacturer’s instructions.

Reconnect the negative battery terminal.
Open and close the sunroof several times to ensure it operates smoothly.
