how to fix this annoying problem. The AC drain plug gets clogged and the AC condesation spils into the passenger compartment of your car.
You can fix this problem from the inside of your car. The drain pipe connects to the firwall right by the gas pedal. You can drill a small hole ino the pipe and clean it out using a coat hanger. Push the coat hanger in both directions throught the firwall and into the Heater/AC unit. Just use some putty or silicon to repair the hole, but make sure you can get it off again because it will clog again over time.
I have taken pictures of the location of the drain pipe from inside the car and in the engine compartment. Look for the white coat hanger in the pictures.
