    today bought a belt put it on started the car and turned on the a/c it blew hot air (i was hoping it would blow cold) the pulley was turning but the other part turned slowing for a minute then stopped does that mean my compressor is bad?

    I feel for you. Suppose to hit 101 up there tomorrow.
    My AC quit working at the house too. It was 100 in Raymond today!!!!
    Humidity is through the roof.

    Either the compressor is locked up or the clutch is slipping. Most likely the compressor.

    Don't give up just yet.
    Get a set of gauges and hook them up, you can likely rent them from Auto Zone.
    You need the system pressures to get an idea of what's going on. It could be as simple as a bad fan clutch letting the high side p[ressure go too high and causing the clutch to slip.
    Turn the compressor clutch by hand. It should turn freely with no binding or rough spots. If so, it's a good sign.

    I hope you'll forgive me for not feeling sorry for you. You're describing our whole summer down here :rant:
