Solution

1. Preparation

Tools Required: Screwdriver set, flashlight, clean rags, water hose, bucket.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery if working on electrical components.

2. Inspect and Clean the Sunroof Seal

Inspect the seal for cracks or signs of wear.
If damaged, proceed to replace the seal (see Step 4).

3. Clear Drainage Tubes

Open the sunroof to access the drainage areas.
Use a water hose to flush the drainage tubes. Allow water to flow freely into a bucket placed below the vehicle.
Check for proper drainage; if blocked, use a flexible wire or compressed air to clear the tubes.

4. Replace the Sunroof Seal (if necessary)

Tools Required: New sunroof seal, adhesive (if required).
Remove the old seal carefully to avoid damaging the frame.
Clean the surface where the new seal will be applied.
