Control Module HVAC: Description and Operation
Blower Motor Speed Control
Blower Speed Controller
DESCRIPTION
The function of the blower speed controller is to convert low power signals from the EATC control assembly to a high current, variable ground feed for
the blower motor.
OPERATION
Blower motor speed is infinitely variable and is controlled by the electronic control assembly software and blend door actuator position. A delay function
provides a gradual increase or decrease in blower motor speed under all conditions. There is a high blower relay integrated into the blower speed
controller which provides power for maximum air flow in the HI blower position.
CAUTION: The system should not be operated with the blower motor disconnected. Damage may occur to the electronic blower speed controller if
cooling air is not provided by the blower motor.
