    I was wondering where the a/c drain hose is located. I think the moisture on my passenger side floorboard is from a/c condenstation. Does anybody know where to find this drain hose?

    Could be the heater core.

    You have to open the evaporator housing to get to the tube. If your not getting too much water on the floor, I'd get some Permagum or RTV, and seal the seam where the evaporator housing meets the firewall.

    I'm so poor I can't even pay attention [​IMG]

    Pugsly has it right. The A/C part is under the hood. I think the drain is just a weep hole formed into the housing. If it were plugged it could back flow in the area around the heater core but that's pretty rare and the water would have to be a couple inches deep. Run the A/C and see if you see it dripping behind the passenger side front tire. If it's driping it's not plugged. You sure it isn't antifreeze? Thats what does leak into the truck.
    Some other things to check would be leaks around the windsheild and rust through around the cowel.

    It's not my damn planet monkey boy!
