Blower Motor Speed Control

The HVAC module sends a PWM signal to the blower motor speed control to control the blower speed. The blower speed control provides variable ground feed for the blower motor to control the speed. A delay function provides a gradual increase or decrease in blower motor speed under all conditions.
