Where is the Mazda6 sunroof drain tube located?

The sunroof drain outlet is located at the front door hinge. Sunroof drainage outlets: If your car's sunroof frequently leaks, it's likely due to a clogged drain tube preventing rainwater from draining properly, causing water to seep into the vehicle through gaps. Engine drainage outlet: The engine drainage outlet is most prone to clogging. If you notice poor drainage during rain, water may spread to the engine compartment, potentially causing starting issues. Vehicle condensate drain outlet: The car's condensate drain outlet is typically located below the evaporator box. Normally, if you find a puddle of water under your car, it indicates an issue with the condensate drain outlet.

I've been driving a Mazda6 for several years and always clean the sunroof drainage tubes myself. The four drainage tubes are located at the four corners of the roof: the front two are hidden inside the A-pillar trim panels, with their outlets at the lower edges of the windshield in the engine compartment on both sides. You can see them by lifting the small rubber covers there. The rear two are harder to find, running down along the C-pillars with their outlets above the rear wheel arch liners. You'll need to remove the trunk trim or wheel arch liners to clean them thoroughly. Last time my roof leaked, it was because the rear drainage outlets were clogged with mud and sand. It took me half a day to clear them with thin wire. A reminder: don't pull the tubes too hard when cleaning—the plastic connectors on older cars are very brittle. It's best to pour some water quarterly to test the flow rate and prevent the interior from flooding during the rainy season.

Last year, I found water accumulation on the front passenger floor mat of my car. After a long inspection, I discovered the sunroof drain tube was clogged. The drainage tube layout of the Mazda6 is quite typical: the front two tubes extend downward from the A-pillars, with their outlets located in the engine compartment near the base corners of the windshield. You can see the drain holes by lifting a coin-sized rubber flap. The rear drain tube is hidden inside the C-pillar, running from the rear corner of the roof to the frame near the rear wheel, positioned quite low and prone to leaf accumulation. If you're doing it yourself, keep a flashlight handy for better visibility—folding down the rear seat backrest can help you see part of the tube's path. A pro tip is to use a motorcycle fuel hose as a cleaning tool; its softness prevents puncturing the drain tube. Also, avoid parking under trees regularly, as tree sap and leaves are notorious for clogging the outlets.

Maintaining the sunroof drainage pipes on a Mazda6 is quite simple for owners. There are four pipes in total: the pipes on both sides of the front sunroof run down along the A-pillars of the windshield, and the outlets can be found on both sides of the rear baffle in the engine compartment; the drainage pipes at the two corners of the rear sunroof pass through the C-pillars, with outlets located near the rear wheel arches. I found that the front pipes are easier to clean—just squat down, lift the rubber flap of the engine cover baffle, and use an air gun to blow them clear. The rear outlets are partially covered by the wheel arches, so cleaning requires patience. A bicycle pump connected to a hose works well as a tool, but never use an iron wire as it can easily puncture the pipes. Be sure to check them during the transition between summer and autumn, as insects love to build nests at the pipe openings.
