Rear Blower Motor Speed Control - Vehicles With: Quadruple Zone Automatic Temperature Control
WARNING: This page is about a different car, the 2020 Lincoln Aviator. However, it is still accessible from the selected car via links, so may be relevant.
The rear blower motor speed control is located in the right rear panel by the D pillar. The rear blower motor speed control is a solid-state switch that uses a PWM signal from the RHVAC control module to determine the desired rear blower motor speed and varies the ground feed for the rear blower motor to control the speed. A delay function provides a gradual increase or decrease in rear blower motor speed under all conditions.
