Electric windows are installed in all four doors. The driver's front window incorporates a self-contained 'Anti-trap' regulator, which features one-shot up and one-shot down functionality. All the passenger windows are hard wired and are powered via the window lift relay in the Central Junction Box (CJB). Should any of the passenger windows have opposing up/down requests from two separate switches, for example, the drivers door switch and the switch on the operating window, then the operation of that window will cease, until one or both of the switches are released.
