Blower Motor Speed Control
WARNING: This page is about a different car, the 2004 Lincoln Aviator. However, it is still accessible from the selected car via links, so may be relevant.
The blower speed control:
- Is located on the heater core and evaporator core housing near the blower motor.
- Converts low power signals from the DATC 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.
- 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.
