The AC climate control panel allows the driver to control the HVAC heating, ventilation, air conditioning system by adjusting the control knob switches for the desired airflow, speed and temperature of the air inside the vehicle. If your AC system is acting up, outside air and inside air doors flap intermittently even when the AC is off or simply stops responding to your specific temperature settings or the behavior of the air seems inconsistent then you may have a problem with your AC heater climate control panel. The A/C Climate Control Module can be easily located on the center of the dash panel and can easily be accessed by removing the whole front dash panel.
