Blower Motor Speed Control

The A/C blower motor speed control is located under the A/C evaporator housing, near the blower motor.
^ The function of the A/C blower motor speed control is to convert low power signals from the electronic automatic temperature control module to a high current, variable ground feed for the blower motor.
^ A/C blower motor speed is infinitely variable and is controlled by the electronic automatic temperature control module software.
^ A delay function provides a gradual increase or decrease in blower motor speed under all conditions.
