Rear Windows

The Rear Window Switches are tied in a series circuit to the Master Switch Assembly. At rest, each switch contact is tied to ground through the Master Switch Assembly. When the master switch is operating a rear window, battery voltage is applied to one side of the associated Rear Window Motor. The motor drives the window in the corresponding direction.
When a Rear Window Switch is operated, battery voltage is applied to the Rear Window Motor through the Master Switch Assembly's Rear Window Locknut Switch. The motor drives the window in the corresponding direction. If the Rear Window Lockout Switch is "SET" (open), control of the Rear Window Motor operation from the Rear Window Switches is disabled.
