Manual Temperature Control

The body control module interfaces with the A/C heater control head via hardwired circuits. Information for the temperature setting is supplied to the body control module via a potentiometer. The rear defogger switch, A/C switch and the mode setting is supplied via a resistive multiplexed circuit. The system ON/OFF status is supplied by a dedicated circuit. The BCM drives the A/C and rear defogger indicator lamps via hardwire to the A/C heater control head.
