    Actuator in dash. Under the glove compartment if you remove that plastic piece 3 actuator motors. Fan speed, temp and direction. Don't remember which is which but it's simple fix. Remove the panel and you'll see them. Could be the door that actuator moves is sticky or stuck too but likely the actuator itself.
