How To Clean Sunroof Drain?

Last Updated on October 6, 2023 by Matthew Lloyd

Cleaning the sunroof drain tubes is essential to ensure proper water drainage. Sunroof drains can become clogged due to debris accumulation, leading to water leaks and potential damage to the car’s interior. To clean the drains, locate the front and rear drain holes, remove any necessary trim pieces, and use a weed whacker line to clear obstructions. Test the drainage by pouring water into the sunroof tray and confirming it flows through all the drains. Regular maintenance and preventive measures, such as keeping the sunroof area clean and free of debris, help maintain the functionality of sunroof drains.

Why Sunroof Drains Get Clogged?

Sunroof drains can become clogged due to the accumulation of debris, including leaves, pine needles, dirt, and other small particles. Over time, these materials can obstruct the drain tubes, preventing proper water flow and causing backups.

• Water Leaking into the Interior: One of the most noticeable signs of clogged sunroof drains is water leaking into your car’s interior. This can occur during or after rainfall, and you may observe water dripping from the headliner, interior roof panels, or door pillars.
• Damp or Musty Odor: Clogged sunroof drains can lead to moisture buildup inside the car. As a result, you may detect a damp or musty odor. This odor can be more prominent when you first enter the vehicle or when the car has been parked for an extended period.
• Stains or Watermarks on the Headliner or Interior Roof Panels: When sunroof drains become blocked, water can accumulate and leave stains or watermarks on the roof panels. These stains may appear as dark spots or discoloration on the fabric or other materials.
• Water Pooling in the Sunroof Tray or Drain Channels: Another sign of clogged sunroof drains is water pooling in the sunroof tray or drain channels. The sunroof tray is designed to collect water and channel it through the drains. If the drains are obstructed, the water will accumulate in the tray or back up in the drain channels.

Tools and Materials Needed

Before you start cleaning the sunroof drains, gather the following tools and materials:

• Gallon jug or water pitcher
• Small funnel
• Weedwhacker line or similar flexible wire
• Philips screwdriver or cordless jabber
• Trim removal set (optional but helpful)
• Towels or rags for cleanup

Cleaning the Front Drains:

Locating the Front Drains

• The front drains are situated in the corners of the sunroof, on both the driver’s and passenger’s sides.
• You can easily visualize the drain holes in the front corners of the sunroof.

Removing the Bottom Trim Piece

• Use a Philips screwdriver or cordless jabber to remove the four screws securing the bottom trim piece beneath the sunroof.
• With a trim removal tool or your hands, gently pry up the trim piece to release the clips securing it in place.
• Pull the trim piece straight backward to remove it.

Clearing Obstructions with Weed Whacker Line

• Locate the clear drain tube visible after removing the trim piece.
• Feed the weed whacker line through the drain tube to clear any obstructions.
• If you encounter resistance, work the wire back and forth to break up or dislodge the obstruction.
• Once you feel no further resistance, the drain is likely to clear.
• Reinstall the trim piece and screws.

Cleaning the Rear Drains

Locating the Rear Drains

• The rear drains are recessed into the roof and cannot be seen directly.
• Accessing and cleaning the rear drains requires working from the bottom of the vehicle.

Accessing the Drip Tray

• Position yourself beneath the vehicle’s rear, near the passenger and driver-side rear bumpers.
• Locate the drain tube for the passenger side rear sunroof drain, which can be seen exiting the vehicle’s underside.
• Use a weed whacker line to feed the drain tube, ensuring it comes out through the sunroof.

Using Weed Whacker Line to Clear Obstructions

• Feed the weed whacker line up through the drain tube, working past obstructions or bends.
• If you encounter resistance, gently work the line back and forth, twisting it to help navigate the drain tube.
• The line should exit through the sunroof, indicating successful cleaning of the drain tube.

Testing the Drainage

• After cleaning all the drains, it is crucial to test their functionality.
• Pour water into the sunroof tray and observe if it drains properly through all the drains.
• Check for water exiting near the wheels to confirm the drains are clear and functioning correctly.

Preventative Measures for Maintaining Sunroof Drains

To avoid future clogs and ensure optimal sunroof drainage, consider the following preventive measures:

• Regularly inspect and clean the sunroof drain tubes, especially during seasons with increased debris.
• Keep the area around the sunroof clean and free of leaves and other materials.
• Avoid parking under trees or areas prone to excessive debris accumulation.
• Use a leaf blower or compressed air to remove debris from the sunroof tray and drain channels.

Conclusion

Maintaining clean and clear sunroof drains is crucial for properly functioning your vehicle’s sunroof and preventing water leaks. Regularly cleaning the drain tubes and removing any debris or obstructions can ensure smooth water drainage and avoid potential damage to your car’s interior. Conducting periodic tests to confirm the effectiveness of the drainage system will provide you with peace of mind and help maintain a dry and comfortable driving experience.
