72 burb air stopped working?!?
Hello, I have a 72 chevy suburban custom 1/2 ton (original 402bbc, fact tilt, fact front and rear air, fact third seat, original 86k mile, fact front sway bar, fact rear air ride shocks, camper package and many other features) but the other day I was out riding my pride and joy and the air conditioner stopped working. Let me be more specific. The fan for the front air/heat stopped working. The a/c compressor doesn't come on if the fan switch is not on or working. The fan doesn't work in heat mode either. The rear fan still works as it should. I checked the fuses and they are good. I replaced the fan switch with another one that I had and the same problem exists. My question is what volt should I be getting at the fan switch where volts come in to the switch and am I miss seeing a relay somewhere hid under the dash that could be bad. I am only getting about 2vdc at the switch but getting the full 12vdc at fuse block. Oh I did check the fan by jumper and it works. Any help is greatly appreciated. I will post pictures as soon as possible
