300E Doors Locking Themselves

Hey Guys,
I recently got a 94 300E and the doors won't stop auto-locking themselves. You unlock the door to get out and all the doors unlock but they all relock themselves by the time you reach the trunk. So it's very easy to lock the keys in the car and is super annoying pumping gas or unloading the car. Any suggestions?

Check the vacum system and also the circuits for it...

It almost has to be a short in a lock switch (3 total) or wiring. I think the system is behind the back seat, or under it.
