this is a common problem the cables that release the upper and lower latches break. you will need to remove the door panels on the inside of the door to get to the latch. remove the 2 screws from the window latch and the upper panel is just push clips pull the panel out towards you and it will release. the remove the top keepers from the bottom panel and lift the panel up to remove. the latch is right in the middle. 2 cables work the latches. pull the cables to release and open the door. replace the cables and latches to repair.
