Answer
Joe,
The power locks in these cars work on a negative pulse system.  Meaning, there is always 12 volts at the lock, but when you lock or unlock the door, it does a quick 12 volt drop (voltage goes to 0 volts for an instant).  So when you touched to wires together, that probably cause the negative pulse to happen and then you saw the door unlock.

The problem is most likely a faulty switch in the lock/mirror control switch in the drivers doors.  You can have a mechanic inspect and replace the switch if necessary.
Good luck!
