Blower Motor Speed Control

Blower Speed Controller:

DESCRIPTION
^ The function of the A/C blower motor speed control is to convert low power signals from the EATC control assembly to a high current, variable ground feed for the blower motor.

OPERATION
^ A/C blower motor speed is infinitely variable and is controlled by the electronic control assembly software and the A/C electronic door actuator motor position.
^ A delay function provides a gradual increase or decrease in the A/C blower motor speed under all conditions.
^ There is a high blower relay integrated into the A/C blower motor speed control which provides power for maximum air flow in the HI A/C blower motor position.

CAUTION: The system should not be operated with the A/C blower motor disconnected. Damage may occur to the electronic A/C blower motor speed control if cooling air is not provided by the A/C blower motor.
