Fellas I have a blower motor that is working on high only, I have not tried to diagnose anything thought I would ask on here first, I let it run for a while today after 5 minutes it started to make a squealing noise. I turned it off, turned it back on it went away, the heat is working the defrost is working, but the four position switch is only working on high, is this the blower motor or the switch?
