    Does anyone know what would cause the A/C to only work when driving?

    Low refrigerant, bad fan clutch, compressor worn out... The list goes on...

    Welcome James to the forums.
    When you turn on the A/C or set to re-circulation mode, is the electric fan running?
    Probably the best place to start, is having an a/c shop test the high & low side specifications.

    Thank you for the info. The crazy thing is it’s ice cold when I’m driving, but come to a stop or sit idle and it doesn’t blow at all.

    I think his info is that if the contained system refrigerant is low, that’s what happens.

    i guess cold is relative to the OP unless it's measured with a thermometer.
    The engine produces so much heat that you'll feel a difference at a stop.
    Who knows where your location is? perhaps you're in the desert or somewhere hot.
    Too many variables.

    What's happening is I start the vehicle and turn on the A/C and I don't hear the blower motor engage and no air blows. Once I Start driving air starts blowing and its cold but not blowing out as hard as it should when i put it on high. I'm assuming blower motor or possible resistor. I waned to see if anyone encountered this issue before just throwing parts at it. I am in Florida BTW.
