Hello, My 2011 Prius A/C started blowing cold air as usual when I turned on the car. When the car is in motion, the air goes from cold to hot. I saw a thread on this which said it was most likely one or any of the three actuators in the HVAC box that is possibly stuck. My thought is that the thermostat may be stuck. Well, yesterday I reset the hybrid system, and everything is back to normal. A/C is blowing cold air again. Any ideas?
When you say, "I reset the hybrid system". Do you mean you shut the car off, waited a minute and restarted it? I once had an issue with the HUD screen, a shutdown and restart fixed it. Another couple of times my cruise control went on the blink. A shutdown and restart fixed it each time. Or do you mean, shut down, disconnect the 12vdc battery for a minute, re-connect and restart?
When I first bought our 2011, the dealership Service Manager warned me about voltage spikes on the 12vdc battery terminal as responsible for burning out computer chips in the vehicle. According to him, anytime you jump the vehicle or disconnect/re-connect the 12vdc terminals you risk frying chips.
