To know for sure if *your* 2003 Dodge Ram 2500 has power windows, you should:
* Check the windows: The easiest way is to simply try the window switches on the driver's door.
* Look at the door panels: Power window switches are usually obvious on the door panels.
* Check the owner's manual: If you have the original owner's manual, it will list the features included with your specific truck's trim level.
* Check the window mechanism: If you have access to the inner door panel, you can visually check for the electric motor and related components. This requires some disassembly.
If they're not working, the problem could range from a blown fuse to a faulty switch, motor, or wiring.
