A/C Blower Motor Speed Control
WARNING: This page is about a different car, the 2002 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
The A/C blower motor speed control (19E624) is located on the A/C evaporator housing, in the engine compartment.
- 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 (18527).
- 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.
