OK THIS IS MY PROBLEM WHEN I START MY CAR SOMETIME THE AC COMES ON BUT ONLY ON HIGH AND SOMETIME NOT, I ALREADY CHANGED THE BLOWER RESISTOR THE AC CONTROL PANEL AND PUT IN A NEW BCM. WHEN I SHAKE THE IGNITON SWITCH THE FAN KICKS ON SOMETIMES,BUT WHEN I TRUN THE SWITCH FROM HIGH TO LOW IT BLOWS OUT THE AC AND MY IMFORMATION DISPLAY PANEL. WHERE DO I LOOK NEXT. COULD IT BE MY IGNITON SWITCH OR MAYBE A GROUND WIRE. WELL THANKS FOR YOUR HELP.

If you can mess with the ignition switch and make it work, then I would start there.Im not real clear on what you mean "blows out the a/c and info panel" do you mean it comes out of the vents and not defrost?

Those are fed through the ignition switch, and if you can make them come on and turn off by messing with the ign switch, i would start there, if nothing else there is a problem with it if you can move it and make things go off and on
