My ac will blow cool but not cold
Question:
I have an 05 gmc sierra denali with 75000 miles. My ac will blow cool but not cold. It has enough freon. I”ve been told that there is an actuator behind the dash that tells the ac to blow cool or cold. They said the actuator is out. What do you think?
Answer:
This sounds to be correct, they are talking about your “Blend door actuator” this actuator separates the A/C evaporator coil and the Heater core to adjust the temperature of your vents. If this actuator is stuck between both, then you will have the situation you described.
