    01 Dodge Ram 1500 Heater/AC Problems
    Hi There,

    I have a Dodge Ram 1500 2001. I bought it used and it seems to have heater issues. Whenever I have the AC on and I slow down or go down hill the heater will all of a sudden kick on.

    Any thoughts on how I can fix this?

    Sounds like a vacuum problem. Check all your vacuum hoses.

    Replace the heater control switch with one from a wrecked Dodge Ram - I did and it fixed the problem. Part of the vacumn lines/hookups are bad on the switch.

    There is a flap located in the dash (have to remove dash to get to it) when you stop or slow down you may here a little bump sound... it's closing turn fan off and accerlerate and turn it back on it will come back on... this is a big problem in Dodge trucks that year...
