ARe there any on line parts diagrams of the door latch assemblies for a 93 100s?

 

What exactly is broken?

 

The interior handles on both the front and rear passenger doors no longer open the doors from the inside.
ALso, unlocking the car requires first unlocking the passenger side door. Unlocking the drivers side door no longer opens the other doors on the second click. Alarm no longer disengages from the driver side door.

 

I think that the problem might be with the central locking and antitheft system. It might be a problem with the pump or the accompanying electronics or switches.
