Solution

1. Preparation

Gather necessary tools and materials:
- Compressed air canister or a vacuum with a nozzle attachment
- Soft brush or cloth
- Water
- Funnel (optional)
Safety warning: Ensure the vehicle is parked on a level surface and the ignition is off.

2. Access the Sunroof Drain

Open the sunroof fully to access the front and rear drainage channels.
Use a soft brush or cloth to remove any debris or dirt from the sunroof channels.

3. Clear the Drain Tubes

Locate the drain tubes at each corner of the sunroof.
Use compressed air to gently blow through the drain tubes, starting from the sunroof area down to the exit points. This will help dislodge any blockages.
If using a vacuum, insert the nozzle into the drain openings and pull to remove any debris.

4. Test the Drainage

Pour a small amount of water into the sunroof channels using a funnel (if necessary).
Observe if the water drains freely from the exit points located under the vehicle or near the fender wells.
Make sure to check both front and rear drain tubes.

5. Reassemble

Once confirmed that the drains are clear, close the sunroof.
Check for proper sealing and operation of the sunroof before finalizing.
