If the doors open and close, they aren't "stuck" make sure all the little bolts are off the bottom of the hinges, disconnect the power cords, and the retention strap. Maintain control of the door so it won't swing all the way open and damage anything. Roll down the window, reach an arm through grab the bottom of the door and firmly pull upward as you slightly rock the door in an open/close motion until the hinge seperated. Be prepared for when it seperated that you don't lose your balance or control of the door.
Pre plan where you are going to put the doors once you take them off.
Hope this helps.
