All, I've read posting on this topic and followed most diagnostics mentioned. I've ruled out; fan motor, fuses, relays, resistor, and performed a HVAC diverter test w/o blower running I heard the doors moving. The A/C works, compressor clutch engages, and at higher road speeds cool air is felt on the floor probably from an A/C ram air effect. Put 12v to the blower motor and it functions fine. During my vehicle electrical check with key-on or engine running, I did not have voltage at motor, relay, and resistor. Next I'm going in for the switches themselves. Is there something else I should check that is less obvious I overlooked ?? Do A/C, Fan, Diverter switches go bad for a with 75,000 mi 2009 redline. Welcome your responses.
