Just as a few questions - when you disconnected the door at the pillar, I assume that lock doesn't actuate - it just sits there quietly.
If you were to get inside the car and manually lock a door by pushing down the button, does it unlock properly when you hit the button, or does it also click but not unlock?
The first test is just curiosity - make sure you've got the right disconnect. But I suspect you'll fail the second test - it won't unlock, either.
I think you've got a bad ground or power connection to the central locking module. Most likely the ground. To engage the lock actuators, the module hits them with a one second electrical pulse. This actually takes a decent amount of current. If you've got a bad ground, there won't be enough current to actually engage the locks - just enough to cause the actuators to wiggle and thump. I've seen this on cars with a really low battery. Since I assume your car is starting and running OK, a low voltage at the module would cause the same results. As an example, get in, close the door, and hit the lock button. Since the dome light is probably on, I would expect it to dim for a full second. If it doesn't, I'd suspect the ground. Heck, I suspect the ground anyway.
Is the problem better if the car is running? The system voltage is higher with the car running, and that might just be enough to engage the locks.
