Nov 22, 2017

Welcome to Grafco Electric's comprehensive guide on cleaning out plugged sunroof drains. If you're experiencing leaks or water accumulation inside your vehicle due to clogged sunroof drains, this step-by-step tutorial will help you resolve the issue and restore the optimal functionality of your sunroof system.

Understanding Sunroof Drains

Before we delve into the process of cleaning out plugged sunroof drains, let's briefly understand what they are and why they get clogged. Sunroof drains are small channels or tubes designed to carry rainwater and other liquids away from the sunroof and towards the vehicle's exterior. Over time, these drains can become blocked with debris such as leaves, twigs, or dirt, preventing proper water drainage and causing leaks or interior damage.

Gather the Required Tools

Before starting the cleaning process, it's essential to gather the necessary tools. You'll need:

  • Screwdriver set
  • Flexible wire or coat hanger
  • Cleaning solution (mild soap or specialized sunroof drain cleaner)
  • Clean, lint-free cloth
  • Water source
  • Bucket or container

Step-by-Step Guide to Cleaning Sunroof Drains

Follow these detailed steps to clean out your vehicle's plugged sunroof drains:

Step 1: Identify the Drainage Points

First, locate the drainage points of your sunroof system. These drains are usually located in the corners or along the sides of the sunroof opening. Consult your vehicle's manual if you're unsure about their exact location.

Step 2: Remove the Sunroof Tray or Panels

Next, remove the sunroof tray or panels to gain access to the drains. This step may require using a screwdriver or following specific instructions provided in your vehicle's manual. Take caution and ensure proper safety measures when working with interior components.

Step 3: Inspect and Remove Debris

Once you have access to the sunroof drains, carefully inspect them for any visible debris or obstructions. Use a clean cloth or your fingers to remove any loose debris and dispose of it properly. This will help clear the initial blockages.

Step 4: Use the Flexible Wire or Coat Hanger

To tackle more stubborn clogs, take the flexible wire or coat hanger and gently insert it into the drain opening. Slowly maneuver the wire back and forth to loosen and dislodge any debris lodged further down the drains.

Step 5: Flush the Drains

After loosening the blockage, it's time to flush the drains to remove any remaining debris. Fill a bucket or container with a cleaning solution - either a mild soap and water mixture or a specialized sunroof drain cleaner. Pour the solution into the drain opening and let it flow through the drains, flushing out any remaining debris along the way.

Step 6: Repeat if Necessary

If you notice that water is still not draining properly or suspect there might be additional blockages, repeat the previous steps until the drains are completely clear. It's important to ensure thorough cleaning to prevent future issues.

Prevention and Maintenance Tips

To maintain the cleanliness and functionality of your sunroof drains, consider implementing the following preventive measures:

  • Regularly inspect and clean the drains as part of your vehicle maintenance routine.
  • Remove any debris on the roof or around the sunroof opening that may potentially enter the drains.
  • Avoid parking or driving under trees or in areas where leaves and twigs are abundant.
  • Consider installing a sunroof deflector or shield to minimize the accumulation of debris.


By following the step-by-step guide provided in this page, you'll be able to effectively clean out plugged sunroof drains and ensure the optimal functioning of your vehicle's sunroof system.
