    My 86 GMC dually A/C will not work. I can ground the clutch assembly and my A/C will work and it gets cool but I can not get it to turn on by the switch on the dash. Does anyone have a wiring diagram on how it works.

    Thanks for the help but I figured it out. When I changed the clutch(transmission) I missed a ground wire so the A/C was not grounded.
