I just installed a factory A/C setup in my 72 Blazer and got everything wired in. The problem I have is that when I turn on the ignition, the heater fan blows on high, and no matter where I place the fan switch, it continues to blow on high and I can't turn it off. Does anyone have any ideas on where I could begin to fix this problem? Thanks
