Q: Q: AC blowing hot air

asked by on

My AC blows hot air on the passenger's side sometimes.

This is a common issue, and as a matter of fact, this has happened to me. The ac system uses electrical motors that are called actuators to move the blend doors behind the dash. These doors direct the air to the proper areas for heating or cooling before coming out of the vent. If the actuator fails, the door will not work properly and you get hot air when you want cold. The solution is to replace the actuator. Depending on the ac system you can have several actuators. They are located behind the dash and depending on which one failed, dash removal might be necessary. I suggest seeking help from a qualified mechanic, such as one from YourMechanic, to inspect your AC to figure out which one needs replacing.
