about 8 months ago my ac went out, it wasnt blowing any out from any vents. I replaced the blower motor resistor and that brought the ac back on for about 2 months, then it did the same thing and went out again. I then replaced my blower motor this fixed the problem for about 6 monts, about 2 weeks ago the problem reaccured. I tested the blower motor by directly wiring the motor to my battery and it works fine. I took my multimeter and checked the voltage coming fromthe resistor and I have voltage and the connector for the motor coming from the resistor also has voltage. I have check the compressor and it too does work. I have been working on cars for years now and im lost, I have checked fuses and relays. Ford even let me swap resistors just to make sure and its still dead. I believe there is a short in the system, what do yall think?
