Sounds like the control unit may be toast - but in addition to the other
suggestions, maybe it is the microswitch located on the door key lock inside the
door?
I only offer this because it is a mechanical part that could break in some wierd
way. Control unit failures seem pretty rare - but they do happen. AFAIK, this is
a V8 only part - so it will be expensive and hard to get - making a thourough
debugging worth your time.
To debug - as always - you have to "think like a computer". Any control unit
generates outputs based on inputs. If the inputs are all correct, and the output
is wrong then the control unit is bad - assuming all wireing is as it should be.
If you do end up diagnosing the control unit, carefully remove the cover and
inspect the relays inside. You may get lucky and find a mechanical problem
inside (like a broken spring or pitted contact) that is easily fixed.
