Non-Dimmable Backlighting

When the accessory relay is energized, voltage is supplied to the door lock control switches and the master window switch, turning on switch illumination. If the master window switch is in the windows UNLOCK position, voltage is supplied through the master window switch to the passenger window switch, the RH rear window switch and the LH rear window switch allowing the windows to operate and illuminating each switch. If the master window switch is in the windows LOCK position, the circuit is opened preventing illumination of the passenger window switch, and both rear window switches.
