Express Down Feature

When the LH front window switch is pressed to first detent in the "DN" position, the express down circuit within the Master Window Switch engages and applies voltage to CKT 163. The LH front window moves to the fully open position. When the LH front window reaches its mechanical limit, the current draw to this motor increases significantly. The express down circuits in the Master Window Switch senses this current draw and removes power to the Window Motor.
