Temperature Control Selector
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2001 Dodge Intrepid, 2001 Chrysler LHS, 2001 Chrysler Intrepid, 2001 Chrysler Concorde, and 2000 Dodge Intrepid. However, it is still accessible from the selected car via links, so may be relevant.
Temperature selector controls a potentiometer (POT), which signals temperature (blend air) door actuator. Changes in voltage across a resistor changes door position through full range of hot and cold. Clockwise rotation increases temperature setting. Counterclockwise rotation decreases temperature.
