Hey guys maybe someone here can help with a little issue I am having. I have a 1991 Toyota 4X4 22RE (4cyl) 5spd with AC. When running the AC, the black air box (I call it) where everything is boxed up under the box gets alot of condensation on it, and drips alot of water onto the floor board. Its not the heater core, I checked that first thing to be certian. What in the world is causing this, and how do I correct it? Any ideas, or anyone know what to do?
