Auxiliary Blower Control Lever (Front Mounted)
WARNING: This page is about a different car, the 2002 Mercury Villager. However, it is still accessible from the selected car via links, so may be relevant.
Lever controls blower motor speed of auxiliary system. Lever has 6 positions: OFF, REAR, 1 (low), 2 (medium-low), 3 (medium-high) and 4 (high). See Fig 1. When not in OFF or REAR position, lever overrides speed setting of blower switch on auxiliary control panel. Placing lever in REAR position allows auxiliary system to be controlled from auxiliary (rear) climate control panel. Placing lever in OFF position completely turns off auxiliary system.
