Introduction
The purpose of this guide is to show you how to clear the sunroof drains on a 2019 series Volkswagen Atlas. Occasionally, these drains become clogged with sand or mud and that can cause water to remain in the sunroof channels and will eventually drip into the cabin of the vehicle. This simple repair will prevent that from happening in the future.
Before beginning this guide, power off the ignition, place the car in park, and engage the parking brake.
Tools
-
-
While holding down the windscreen with one hand, use the other hand to grip the trimmer line close to the end and locate the drain opening.
-
Begin feeding the trimmer line into the drain opening and continue pushing the line down the drain in short segments.
-
If the line stops feeding into the drain and you haven't used about 5-6 feet of line, give it a gentle push to attempt to get it to continue.
-
If the line will not go in any further after a gentle push, remove the line and continue to the next step.
-
-
-
To test the drain, pour a good amount of water into the drain and watch it move down the channel and into the drain opening.
-
-
-
To check that the blockage is cleared, look under the vehicle for water on the ground. The water should appear slightly behind and toward the interior of the front tire of the side you were working on.
-
If this was successful, repeat steps 3 through 5 on the other side of the vehicle.
