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 cabs models.

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" under Ignition Positions .

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 positon, until the window is at the desired position.

Lock-Out Switch

If you have power windows on a crew cab, the driver's door power window switch has a lockout feature. The lockout switch is located in front of the window switches. This feature prevents all windows from operating, except from the driver's position. To engage the lock-out feature press the switch, and an indicator light on the switch will illuminate. To disengage the lock-out feature press the switch again, and the indicator light will turn off.
