Solution

1. Preparation

Gather tools: screwdrivers, compressed air, a small flexible rod, and a clean cloth.
Park the vehicle on a level surface and ensure the sunroof is fully closed.

2. Inspect and Clean

Sunroof Seal Inspection:
- Examine the rubber seal around the sunroof for any signs of damage or wear.
- Clean the seal with a soft cloth and a mild detergent to remove dirt and debris.
Drainage Tube Cleaning:
- Locate the drainage tubes, typically found at the corners of the sunroof frame.
- Use compressed air to blow out any obstructions in the tubes.
- If blocked, insert a flexible rod gently to help dislodge debris.

3. Repair or Replace Seals

If the seal is damaged:
- Remove the old seal by carefully prying it off with a flat tool.
- Clean the area where the new seal will be applied.
- Apply a new sunroof seal, ensuring it adheres properly and is evenly placed.

4. Test the System

Once repairs are completed, run water over the sunroof to check for leaks.
Ensure that all drainage tubes are clear by pouring water into the sunroof channels and watching for drainage.
