|B0211 CADILLAC code description

The Auxiliary Blower Motor Control Module is an interface between the Heating, Ventilation, and Air Conditioning (HVAC) Control Module and the Auxiliary (Rear) Blower Motor. The auxiliary blower motor control module has 5 circuits: a B+ input, ground, a control signal from the HVAC module, a B+ output and a low side Pulse Width Modulation (PWM) control to the Auxiliary (Rear) Blower Motor. The HVAC control module provides a low side (PWM) signal to the auxiliary blower motor control module in order to request the auxiliary blower motor speed. The auxiliary blower motor control module grounds the blower motor using a low side PWM signal in order to vary the auxiliary blower motor speed.
