Blower Motor Speed Control

The A/C blower motor speed control:

• Is located on the A/C evaporator housing, in the engine compartment.
• Converts low power signals from the dual automatic temperature control module to a high current, variable ground feed for the blower motor.
• Varies the blower motor speed and is controlled by the DATC module software.
• Provides a gradual increase or decrease in blower motor speed under all conditions by use of a delay function.
