Express Down Window Operation

When the LH Front Window Switch is held in the "DN" position for just over 0.3 seconds, the express down circuit within the Master Switch Assembly engages and applies voltage to CKT 165. 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 Switch Assembly sense this current draw and remove power to the Window Motor.
