All of a sudden my great working a/c goes hot on me and the refrig. charge is good. I'm an hvac tech! My codes tell me the steering wheel temp and fan controls are screwed up. Can this be over ridden effectively?

Are the HVAC temp controls on the dash working? As in, can you adjust the temp setting readout?

Have you checked the DTC's? Maybe you have a bad temperature actuator.
