my Tesla Model 3 has a leaking sunroof, what should I check?

Solution

1. Preparation

• Gather tools and materials.
• Ensure the vehicle is parked on a level surface.
• Disconnect the vehicle's battery to avoid electrical issues.

2. Inspect and Clean Drainage Channels

• Locate the drainage holes at the corners of the sunroof.
• Use a soft brush or compressed air to clear any debris or blockages in the drainage channels.
• Pour water into the sunroof area to test if it drains properly.

3. Replace Sunroof Seals

• Carefully remove the old seals using a trim removal tool.
• Clean the surface where the new seal will be applied.
• Apply the new seal, ensuring it is seated properly and evenly along the entire edge.
• Use a sealant if recommended by the manufacturer.

4. Test Sunroof Functionality

• Reconnect the battery.
• Operate the sunroof to check for proper opening and closing.
• Verify that no water leaks occur during the operation.

5. Final Inspection

• Once repairs are complete, conduct a final check for any visible leaks.
• Test the drainage by pouring water over the sunroof and ensuring it flows out the drainage channels without pooling.
