Where are the drain holes sunroof?
Similarly, you may ask, where does the sunroof drain?
The sunroof assembly has gutters going all of the way around it to catch any water that gets by the sunroof glass. The water then makes its way to drains on the corners of the sunroof housing under the glass, where it flows down plastic tubes inside the body of the vehicle, draining out onto the ground.
Correspondingly, how do I know if my sunroof is clogged?
Pour a small amount of water into the drains and look underneath your car to see if it's draining. If there's no puddle on the ground, you have a clogged drain. To clean your drain, use compressed air or a cotton swab to dislodge any debris that could be clogging the tube.
Although they seem waterproof, sunroofs and moonroofs really aren't. They use a rubber seal around the edges to keep most of the water out when they are closed, but under the glass or metal cover around the edge is a drainage system. Generally, the water is routed to the front of the sunroof's under portion.
