One or more heater & AC (HVAC) temperature and/or air delivery mode door actuator may fail, resulting in improper temperature or air delivery. If this occurs, fault code(s) should be stored in the HVAC control module which should assist in diagnoses.

    A/C on the drivers side only will start blowing hot air. I have to turn the vehicle off and then on again to restart the cool air blowing. It may stay cool for hours or 2 mins. before it begins blowing hot air again. Sometimes it begins blowing cool air again on its own.

    AC/Heat both run but when I have either one set to run high, the outcome is very limited as though something is restricting it from exiting fully from the vents.
