Automatic Door Lock
My 85 4000s door locks recently stopped working and I am now locked out of my trunk. I am unable to find my master key so this is a problem.
Unlocking the driver's door seems to do nothing at all other than the obvious. However locking the driver's door, if the other doors are unlocked, activates the pneumatic pump in the trunk, which I can not get to, but only locks the two rear doors and not the passenger's door.
Is it possible that manually locking the doors may have disrupted the normal functioning? If so is there a way to reset the system? Or do I have to take out the rear seat to get into the trunk and try to test the pneumatic system, which I do not really know what I am looking for or at, and maybe replace parts?
In other words I am wondering if there is a trick to fixing the problem.
I would be grateful for any advice and suggestions.
