Blower Motor Speed Control

The blower motor speed control:

• is located on the evaporator core housing behind the suction accumulator.
• varies the blower motor speed and is controlled by the EATC module.
• uses low power signals from the EATC module to control a high-current, variable ground feed to the blower motor.
• has a delay function to provide a gradual increase or decrease in blower motor speed under all conditions.
• controls the integral high blower speed relay which is engaged when maximum fan speed is selected.
