I have a 2007 Hummer H3, I5. The HVAC temp dial is not working properly. On full cold it works fine. Move it 1 click toward warm it goes full warm. I've replaced the left and right actuators that would affect air temp flow. During HVAC calibration both actuators move. When trying temp dial, only the left actuator moves and it goes the full 90 degrees. I've also replaced the HVAC control unit (entire unit with control dials). What else should I be reviewing?
have the same problem?
