I have a 95 accord EX sedan, one of the passager doors ( the one behind driver seat) doesnt want to unlock when i unlock all the doors. When i try to unlock it, there is this sound like a motor or something, but it does lock, but doesnt unlock. Help plz!!!

 

Take off the inside door panel. Look around to find the lock motor. There's usually some kind of push-rod linkage from the lock motor to the lock itself. Check to see if something's disconnected or loose, either the linkage or the wiring. Or maybe the lock motor itself is bad.
