2004 GMC Envoy airconditioner condensation is leaking into the floorboard on the passinger side of my car.?

Question

Does anyone know where the drain pipe is located and how I can unplug it?

Answer 1

Look up under the passenger side below where the a/c lines go into the passenger compartment. You will see a plastic or rubber spout sticking out about a half-inch. It's best not to stick anything up into it, we used compressed air to blow it clean. If you do stick a coat hanger up into it to try to clean the drain, make darn sure you straighten the entire hanger and fold it in half. The evaporator coils are very thin for good heat transfer, and a sharp coathanger end can go right through a coil. Expensive oops. Good Luck!

Answer 2

run a coat hanger up the drain pipe. if it is in the fram rail like a jeep then you can blow it out with air.
