If your vehicle is a crew cab model with power windows, the driver's door will have four switches on it that can control all of the windows. There will be switches located on the rear doors as well.

Your power windows will work when the ignition has been turned to ACCESSORY or RUN.

Press the rear of the switch with the power window symbol on it to lower the window and the front of the switch to raise the window.

Express-Down Feature

The driver's window also has an express-down feature that allows the window to be lowered without holding down the switch. Press and hold the rear of the window switch labeled AUTO for one second to activate the express-down mode.

The express-down mode can be cancelled at any time by pressing the front of the switch. To open the window part way, lightly tap the switch until the window is at the desired position.

Lockout Feature

(Lockout): If you have a crew cab model with power windows, the driver's door will have a window lockout feature. When engaged, this feature will prevent all window switches, except the driver's window switches, from operating. This switch is located above the four window switches on the driver's door. When the switch is not engaged, all windows will return to normal operation.
