Solution

1. Preparation

Tools Required: Screwdriver set, flashlight, soft cloth, water hose.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect and Clean the Sunroof Seals

Remove any dirt or debris from the sunroof seals using a soft cloth.
Check for tears or cracks in the rubber seals. If damaged, they need to be replaced.

3. Clear the Drainage System

Locate the drainage holes, typically found at the corners of the sunroof.
Use a water hose to gently flush water through the drainage holes. Ensure it flows freely without blockage.
If water does not drain, use a flexible wire or pipe cleaner to clear any obstructions.

4. Realign Sunroof Glass (If Necessary)

Check if the sunroof glass is misaligned.
Open the sunroof and locate the adjustment screws on the track.
Adjust the screws slightly to raise or lower the glass for proper sealing against the frame. Tighten to manufacturer specifications.

5. Reassemble and Test

Reconnect the battery and ensure all components are properly secured.
Test the sunroof to ensure it opens, closes, and seals correctly without leaks during a water test.
