My power doors work only when the lock on the passengers side is in the lock or unlock position. the lock is loose, it works but when I push it manually from lock to unlock there is NO "click" it just kind of moves from side to side. What do I need to do to fix it? My jeep came from the factory keyless entry and I dont want to spend 90 bucks on a fob and than another 40 to have them hook a computer up and program it. I know its the lock but which part?
