Power Windows The driver's door has a switch for the passenger's and rear windows as well, if equipped. Your power windows will work when the ignition has been turned to ACCESSORY or RUN or when Retained Accessory Power (RAP) is active. See Retained Accessory Power (RAP) on page 2-23. Press the switch down to lower the window. Pull up the front of the switch to raise the window. Express Down Windows The driver and front passenger windows also have an express down feature that allows the windows to be lowered without holding the switch. Press down fully on the window switch, then release, to activate the express down mode. The express down mode can be canceled at any time by pulling up on the switch. To open the window partway, press the switch to the first depression position, until the window is at the desired position. If your vehicle is equipped with power windows, the controls are located on each of the side doors in the front and rear for crew cab models. 2-17
