Crew cab switches shown


Object Number: 1306950  Size: A3

The power window controls are located on the armrest of each door.

The driver's door has switches for the passenger windows as well. Your power windows will work when the ignition has been turned to ACC (Accessory) or ON or when Retained Accessory Power (RAP) is active. See "Retained Accessory Power" under Ignition Positions .

Pull up the forward edge of the control with the power window symbol on it to raise the window.

Press the forward edge of the control down to lower the window.

Do not hold all four power window switches down for several seconds after the windows have been completely lowered or raised, because the vehicle may blow a fuse.

Express Down Windows

The driver's window also has an express down feature that allows the windows to be lowered without holding the switch. Press and hold the front edge of the window switch for one second 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, lightly tap the switch until the window is at the desired position.

Window Lockout

If you have a crew cab vehicle with power windows, you will also have a window lockout button located above the window switches. This feature disables the rear windows switches when the window lockout button is pressed. To turn the lockout feature on or off, press the window lockout button. When the feature is off, the power windows will operate normally.
