Jay Bob, thanks for all that info, most helpful.

I think I'm going to start by checking out the driver's door lock and see if there isn't a problem with the 'unlock' signal. I'm suspecting that there is a constant unlock signal given to the system from the driver's door, so trying to lock the system from any other door results in the odd behavior.
