How to Troubleshoot the Heater & Air Conditioning Controls in a 2006 Dodge Charger

Save

Chrysler's Dodge 2006 heating, ventilation and air conditioning, or HVAC, controls are rotary knobs. The knobs are used to set optimum interior temperature and air flow. You can close four dash-located vents to partially restrict airflow, and use a button to turn the air conditioning on and off. Another button is for turning the electric rear window defroster elements on and off. You can correct problems with your HVAC controls in the 2006 Charger via troubleshooting.

  • Turn the blower knob clockwise if there's no air being throughput. It's the rotary knob on the left and can be set at one of four speeds and off. "Off" is fully counterclockwise. Make sure the four vents (registers) in the dash are open to fully take advantage of blowing air.

  • Rotate the temperature control clockwise if the Dodge Charger is too cool and counter-clockwise to reduce heat. The air conditioning won't be switched on until you press the air conditioning button. That's the button with the snowflake icon on it. The button will illuminate when it's in the "On" position.

  • Look at the third dial and make sure a zone is selected if the controls you operated in the previous steps don't appear to work right. The knob can be placed in varying positions and distributes heated, or cooled air to the locations depicted on the icons, for example, the floor. Dots between the icons indicate intermediate positions.

  • Press the rear window defroster to clear the rear window. The light will illuminate in the control. The light extinguishes after ten minutes because the defroster automatically turns off after ten minutes.
