My passenger floor is getting wet from the air conditioning system. I checked the air conditioning condensation line and it is clear and unobstructed and seated properly into the transmission hump in the floor.

Upon checking around it looks like water is dripping off of the lower air conditioning line that comes in from the engine compartment and goes into the plastic air box thingy.

Any suggestions on what's going on?

I have the same issue w/ my 93 245 in Dallas. I am convinced that it's due to condensation on the HVAC ait supply ducting. Last weekend I drove rom Dallas to Arkansas and noticed that the ducting was dripping condensation. I read a post in the V8 forum a couple of weeks ago about a guy in FL who reached the same conclusion and insulated his ducting and cured the problem. I plan on doing the same. If the freon line going to the evaporator is leaking, you can get the black gooy insulating wrap at any A/C supply place.
