DESCRIPTION AND OPERATION
Blower speed is determined by the Body Computer Module (BCM) for the temperature data input and the operating mode of the Air Conditioning
System. The Climate Control Panel (CCP) accepts input requests from the driver via the front panel push-button. The input signals determine the
operating mode for the Climate Control System and are sent to the BCM over the data line (Circuit 718).
The output from the BCM at Terminal A9 is variable. If voltage is less than 2 volts, blower speed decreases. If voltage is between 2-3 volts,
