Have 96 Fleetwood. the mat on the shot-gun side is always wet. Where's the hole for the AC drainage and how do you clean it?

Thank you

Its possible that your drain is clogged and its backing up and getting into the car. The drain is on the passenger side out of the bottom of the HVAC module. When the car is running with the AC on you should get condensate from that hose. You can try clearing it gently with a hanger and by spraying it out with a high pressure hose.

Is it clean water? Make sure your heater core is not leaking inside, but I would imagine you would smell that..

There is a rubber elbow that is attached to the evaporator drain at the firewall. Make sure the elbow is not missing - if it is, air movement will cause the evap. housing not to drain and the carpet will be saturated with water. If the elbow is present, it may just be plugged.
