If the air conditioning system is on and vent temperatures are as expected for a/c at certain outlets (typically outlets would measure around 35-40 degrees below outdoor ambient) yet the air blowing from other outlets is "warmer" or indeed "hot", check the position of the heater control valve. If the heater control valve is open (when it’s not supposed to be) AND there are malfunctioning, mispositioned or stuck blend doors, that would explain the hot air. If you want this problem resolved by a certified Mechanic, dispatched by YourMechanic right to your location, please request an a/c and heating systems diagnostic. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
