    Dodge Ram 2500 V10 Quid Cad Short Bed Sport
    I have a 1999 DODGE RAM 2500 v10 Quid Cad short bed
    The A/C works great when I works
    When I slow down or come to a stop it sound like a door closes under the dask it goes from cold air to HOT I have to turn it off and turn it back on after a few secondes it not the door under the glove box that's for inside air or outside air this mush I have found out
    It is a vaclumm I think but I can not fine this second door does any one know
    1 where this door is
    2 where the vaclumis for it.
    I have even gone to Dodge and they don't know or won't tell me unless they do the work
    That is $85.00 a hour and I can afford that.
    Love the truck just hate it in the summer when its 110 outside
    Thank You
    Ken

    Sounds like it may be a vacuum hose leak. See if this link helps:

    If the evaporator coils are freezing up, the air flow will stop. Look for excess water and any freezing on the low pressure hose running from the evaporator coil to the accumulator. In this situation, the fix is simply to replace the A/C Clutch Cycling Switch. There's a shrader-type valve, usually located on top of the accumulator, that simply screws off. No need to worry about freon recovery--very little freon will escape. Coat shrader-type valve with refrigerant oil and screw the new A/C Clutch Cycling Switch on and reattach the 2-pin connector.

    Sorry, I'm not familiar with your truck.
