Solution

1. Preparation

Tools Required: Flathead screwdriver, soft cloth, compressed air, water, bucket.
Disconnect the battery to prevent any electrical issues while working on the sunroof.

2. Inspect and Clean the Sunroof Seal

Carefully run a soft cloth along the sunroof seal to check for dirt or debris.
If dirty, clean the seal with mild soap and water, then dry thoroughly.
Inspect for cracks or tears; if damaged, proceed to replace the seal.

3. Clear the Drainage System

Locate the drainage tubes (typically found in the corners of the sunroof).
Use compressed air to gently blow out any debris or blockages from the tubes.
Pour a small amount of water into the sunroof channels and observe if it drains properly. Ensure it flows out of the drain exits.

4. Replace Damaged Seals (if necessary)

If the sunroof seal is damaged, carefully pry it off using a flathead screwdriver.
Clean the area where the seal was located to ensure proper adhesion.
Apply the new seal, ensuring it fits snugly into the groove.

5. Reassemble and Test

Reconnect the battery.
Open and close the sunroof several times to ensure it operates smoothly.
Conduct a water test by pouring water over the sunroof to check for leaks.
