Where are the Mazda 6 sunroof drainage outlets located?
2 Answers
The Mazda 6 sunroof has one drainage outlet at each of the four corners of the sunroof. When you open the sunroof, you can easily see four small holes, each connected to a hose that leads to the front and rear of the car. If these drainage holes at the four corners become blocked, water cannot drain properly and may seep into the interior. The hazards of blocked drainage outlets and cleaning methods are as follows: Hazards of blocked drainage outlets: If the drainage holes at the four corners are blocked, water cannot drain properly and may seep into the interior. In severe cases, water may flow along the roof to the sunroof motor inside the car. If the sunroof motor is used while powered on, it may short-circuit and burn out. Cleaning methods: Initially, blockages occur at the entrance of the drainage holes, which can be easily seen and cleaned by opening the sunroof. Over time, debris may enter the drainage hoses and move further inside, making it harder to clear. In such cases, it is best to visit a 4S shop and have a professional technician perform the cleaning.
As a long-time Mazda6 owner who's driven it for nearly a decade, I know exactly where the sunroof drains are located. They're hidden at the four corners of the sunroof - just open it and you'll see them. The front drains are at the junctions between the windshield and A-pillars (one on each side), while the rear drains are at the inner corners of the C-pillars. Here's the crucial part: The drain tubes run downward along the interior trim panels of the A-pillars and C-pillars, eventually exiting near the front wheel splash guards and the rear underbody. I learned this the hard way when clogged drains flooded my car. Now every spring I use flexible wire to clear the drains and pour water to test the flow. These tiny holes are absolutely vital.
