The parking brake in my chrysler pacific is stuck. how do u release it?

Is it a "stick" in the console between the driver and passenger seats, or is it a pedal you push down? If it is in the center console, try starting the car, putting it from park into NEUTRAL with your foot on the brake, and pull up on the stick a little while pushing in the button. If the button goes in, push the handle back down, put the car back into park, and take your foot off the brake. I'm not real familiar with the Pacifica, so a description of the parking brake would help.
