Tools Required

Soft cloth or towel
Water
Hose (for testing drainage)

Repair Instructions

Step 1: Clear Drainage Channels

Open the Sunroof
- Open the sunroof to its fully retracted position.
Access Drainage Holes
- Inspect the four drainage holes located at the corners of the sunroof frame.
Clear Blockages
- Use compressed air to blow out any debris that may be clogging the drainage holes.
- If the blockage is stubborn, use a small flexible wire to gently dislodge debris.
Test Drainage
- After clearing, pour a small amount of water into each corner to ensure proper drainage.

Step 2: Inspect and Repair Seal

Examine the Sunroof Seal
- Check the rubber seal that runs around the sunroof for cracks, tears, or signs of deterioration.
Clean the Seal
- Use a damp cloth to clean the rubber seal and the frame of the sunroof to remove any dirt or debris.
Apply Silicone Sealant (if needed)
- If the seal is damaged, consider applying a silicone sealant to the areas where it appears compromised. Ensure that the area is clean and dry before application.

Step 3: Reassemble and Test

Close the Sunroof
- Ensure the sunroof is closed properly after making any adjustments or repairs.
Test for Leaks
- Use a hose to simulate rain and pour water over the sunroof area. Check for leaks inside the cabin.
- Monitor the drainage holes to confirm that water is draining away from the vehicle.
Observe Over Time
- For the next few days, monitor the interior for any signs of moisture or leaks to ensure the problem is fully resolved.

Conclusion

If the sunroof continues to leak after following these steps, it may indicate a more serious issue with the sunroof mechanism or the installation. In such cases, it is advisable to consult with a professional technician or visit a Toyota dealership for a thorough inspection and repair. Regular maintenance and inspection of your sunroof can help prevent future leaks and prolong the life of your vehicle.
