Blower Motor Speed Control

The blower motor speed control is located under the heater core and evaporator core housing, near the blower motor.

• The function of the blower motor speed control is to convert low power signals from the RCC module to a high current, variable ground feed for the blower motor.
• Blower motor speed is infinitely variable and is controlled by the RCC module software.
• A delay function provides a gradual increase or decrease in blower motor speed under all conditions.
