    had this happen once before. if i am on a trip and run my AC for say 3 to 5 hours my floor becomes wet. my drain is clear but i am assuming a crack internally or? my ac runs strong no problems there.

    Sounds like a bad valve on the evaporator.
    It's faction is to keep the evaporator from freezing thus no water leakage from it!:cool:

    Could be a bad expansion valve . Or dirt in the system blocking the valve causing freeze up like mentioned .. If it doesn't do it on short runs around town takes a long time for water to appear on the floor That's usually a sign that the coil is building ice on it (aka freezing up ) blower cant blow air as well (maybe kicking water everywhere ) as air is forced around the solid Icey coil .....

    The drain could be clogged under the truck usually leaves,dirt and pollen are usually the cause

    Dont recall if . Toyota trucks have expansion valves or a inline ac orifice tube
    If its a expansion valve it will be close to the interior coil be small block or round thing . More than likely located inside the black box the heat coil and ac coil sit in .. Proably a sob to get to

    It is fitted to the evaporator, which is inside a box behind the glove box.
    You have to discharge the system,remove both hoses @ the fire wall,&remove that box,which you will open up! You can find the parts you will need online.The system will have to be vacuumed & recharged! :cool:
