New member. My 01 MGM is leaking moisture into cabin thru passinger side firewall. No rain, but still getting wet. I figure it must be a plugged A/C evaporator drain, But I can't figure out on how to unplug it. I tried blowing air down thru the outside air intake well under the wiper cowling but go no results. Any help would be greatly appreciated.

 

Do not know specifically about a 01MGM, but what I would do is go under the car, find the rubber A/C condensate drain hose and run a flexiable tube or wire through the drain hose. If no hose is present, then it is quite possible it fell off and the A/C is draining into the cabin. You will need to replace the hose.

 

Thanks for the quick reply. I've been under the car to try your idea. There is no hose. There is a spout coming from the firewall under the housing that encompases the blower moter, heater core lines, and A/C lines. I tried running a wire into it with no results. The spout is not quite round, the top of it is flat, the bottom 2/3s is like any pipe. Because of it's location, it is impossible to feed a flexable wire into it. I used a stiff wire but could only insert it about 1 1/2 inch straight in not up. Am I going to have to take the dash apart to get to the drain?
