Door Lock Problems

Howdy all.

The wife and I just purchased a ''02 Sebring Sedan with 48k miles on it.  Got it from an old lady who has lost her sight.  Only problem with the car is the door locks.  This car does not have key less entry.  When you go to turn the key in the door lock it can spin all the way around and if you hit just the right spot it will unlock.  Also the drivers side lock/unlock switch does not work and the passenger side switch only unlocks but will not lock.

Anyway I am an electrician by trade and a wannabee shade tree mechanic but I typically only wrench on older cars.  I am not afraid of pulling the door panel but seeing as how it appears that this car does not use a mechanical link for the door lock any of you have a wiring diagram for how things should look?  Also if any of you would know what kind of readings I should be getting while testing the wires?

Any help is appreciated.

Thanks
Kevin
