Control Module HVAC: Description and Operation
POWER MODULE
The blower motor power module is only used in vehicles equipped with Automatic Temperature Control (ATC). It is located on the lower right side of
the HVAC unit housing, and is controlled by the Body Control Module (BCM).
The power module receives pulse width modulated (PWM) signals from the BCM. The power module varies voltage to the blower motor for different
blower speeds based on the ATC software. There are 14 selectable speeds, while the Auto mode provides 256 variations.
