Window Control

Voltage for the power windows is supplied from the central junction box (CJB) to the master window adjust switch when the ignition switch is in the START or RUN position. If the master window adjust switch is in the UNLOCK position, voltage is distributed to the passenger window adjust switch and the rear door window adjust switches (if equipped). If the master window adjust switch is in the LOCK position, the circuit is opened, preventing window operating control at any of the passenger doors. Ground circuits for all the window adjust switches are routed through the master window adjust switch. All windows can be opened and closed from the master window adjust switch regardless of window lock switch position.
