AC is not working at all but all fuses and relays are good. The blower motor has 12volts and when i ground out the other wire it blows. The AC clutch doesn’t engage but i don’t think it is even getting a signal from the temp controls. Can a bad blower motor resistor stop the entire system from operating?



The AC clutch will not engage if the Freon is low. You can test the clutch by jumping across the low pressure switch with a paper clip. Make sure the selector switch for AC is on. The Blower is separate.  Generally if the blower resister is bad the blower will only work on high speed.

More than likely you just need to recharge your air conditioning system. Here is a video that shows you how easy it is to do it yourself.
