* Manual Crank: Older Wranglers and some trim levels use manual crank windows. There's a crank handle usually located on the door panel. Simply turn the handle to roll the window down or up.
* Power Windows with Buttons: Most modern Wranglers have power windows. There's a switch panel, usually on the driver's door armrest, with buttons for each window. Press the button for the desired window to lower it.
* Power Windows with a Switch on Each Door: Some Wrangler models have a switch for each window on each door. You press the button on the specific door's panel to roll that door's window down.
To know for sure, you need to look at the door panel of your specific Jeep Wrangler. If you can provide the year and model, a more specific answer can be given.
