Description & Operation: AEROSTAR

Voltage is present at the master window door lock switch, the right window door lock switch and the power door lock module, at all times, through Fuse Link C, a 30A In-line Fuse and the Black/White wire. With either door lock switch moved to the UNLOCK position, current flows through Fuse Link C, the in-line fuse, the door lock switch and the door lock/unlock control relay unlock coil to ground. The relay UNLOCK coil is energized and its contacts close. Current now flows through fuse link C, the door lock/unlock control relay unlock contacts and the Pink/Orange wire to the door lock motors and the power door lock module. All doors unlock.

With either door lock switch moved to the LOCK position, current flows through fuse link C, the in-line fuse, the door lock switch and the door lock/unlock control relay LOCK coil to ground. The relay lock coil is energized and its contacts close. Current now flows through fuse link C, the in-line fuse, the door lock/unlock control relay lock contacts and the Pink/Black wire to the door lock motors and the power door lock module. If the sliding door is closed, all doors lock. If the sliding door is open, all doors except the sliding door will lock. Then, when the sliding door is closed, the power door lock module outputs power at pin 7 to operate the sliding door lock motor and lock the door.
