The AC drain for the 2009 VW Routan SE is located on the passenger side of the vehicle, near the firewall. It is a small, black rubber hose that is about 1 inch in diameter. The hose is attached to the bottom of the evaporator housing and runs down to the ground.
To access the AC drain, you will need to remove the plastic cover that is located under the glove box. Once the cover is removed, you will be able to see the AC drain hose.
If the AC drain hose is clogged, it can cause water to leak into the passenger compartment of the vehicle. To clean the hose, you can use a small brush or a piece of wire. Once the hose is clean, make sure that it is properly attached to the evaporator housing.
