Sunroof Drain Tube Description

Most sunroofs have narrow drain holes around their edges. Rainwater and other moisture from the outside get drained into these holes through tubes located along the sunroof track and then out from the vehicle’s pillars, roof lining, and footwells. Blocked drains cause water to come out from these tracks and soak the roof sills, floor mats, and seats, especially if the obstruction is near the drain hole.
