Driver Window-Down Input Signal

When the Window DOWN switch is pressed, voltage passes to body control module (BCM) terminal X4-26 via the Power Relay R22 contacts, circuit 638 and the Driver Window DOWN switch contacts X1-13. From BCM terminal X4-26, the current passes through the normally closed contacts of the BCM Driver Window Relay to terminal X1-A PF the Driver Window Motor via BCM terminal X4-25 and circuit 165. Terminal X1-B of the motor is grounded through circuit 164, the Driver's Window UP switch contacts and circuit 650. The BCM microprocessor senses the length of time that the drivers window button is pressed DOWN at terminal X4-26. If the window DOWN switch is momentarily pressed for more than 0.4 second and less than 1 second, the BCM energizes the LTFR Window Relay until the window lowers fully.
