    I was fixingt to replace my ac unit, since my compressor went out. Now I have a couple of issues. My fan motor seems to just be running, even in off postion. The fan switch no matter what way you turn it it will not adjust speed( 0ff 1 2 3 4). It all seems to be that the selector for floor vents, or mixed seems to be stuck. Somewhere i seen that there is a module under the dash that burns out alot. I just need to know what to do,

    :sign0016:To the Site George.......The item your asking about, is the Blower Motor Resistor,which is a Common Problem on the 99" and up Trucks/SUV's.....I would guess that it would be a little different on your 1996"....

    Below is a link showing how to replace the Blower Motor Resistor in a 96" GMC.......but it should be the same for your 96".....

    It sounds like your control head is probably bad. I've seen them do some pretty crazy things. I don't know if you can get one anywhere except the dealer, but you might check on e-bay.
    Good Luck and God Bless

    Ok, Help again I have changed the switch no change. Now could it be the controller or the fan motor. How can I test the fan motor.

    you can test the fan motor..simply by attaching a wire to the positive side of your battery and connected to the positive side of the fan motor.
