Solution

1. Preparation

Gather necessary tools: flathead screwdriver, torx screwdriver set, vacuum cleaner with a narrow attachment, sealant, and cleaning cloths.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect and Clean the Sunroof Seal

Sub-steps:
1. Open the sunroof fully.
2. Carefully inspect the rubber seal around the sunroof for cracks or tears.
3. Clean the seal and surrounding area with a mild soap solution and a soft cloth to remove dirt and debris. Allow it to dry completely.
4. If the seal is damaged, replace it with an OEM part.

3. Clear Drainage Channels

Sub-steps:
1. Locate the drainage holes at the corners of the sunroof frame.
2. Pour a small amount of water into each corner to check for drainage. If water does not flow out, proceed to clear the channels.
3. Use a vacuum with a narrow attachment to suck out debris from the drainage tubes. Alternatively, use compressed air to blow out blockages.
4. Test again by pouring water to ensure proper drainage.

4. Reseal or Replace Sunroof Sealant

Sub-steps:
1. If the seal appears intact but leaks persist, consider applying a silicone sealant to the edges of the sunroof.
2. Clean the application area with rubbing alcohol to ensure a good bond.
3. Apply a thin bead of silicone sealant along the edge of the sunroof frame. Smooth it out with a finger or a tool.
4. Allow the sealant to cure as per manufacturer instructions before using the sunroof.
