blower fan used to come on them go off briefly but would eventually stay on. Then it would only run on high. now it doesn't work at all. compressor seems to work ok, fan run when I ran it on 12v. Fuses are ok. now what?

are these replies to auto air? Because I am not finding the blower resistor or switch. I have a auto air system and this seems to be a manuel air answer

Thank You
