I have a leak in the unlock line going to the left rear door. The pod holds fine. When I tie in just in front of the driver's seat, the line wont hold any vacuum. Is there a rubber connector between the front seat and the pod? Or is the line itself cracked somewhere, most likely where it flexes at the door hinge?

Which one of your many vehicles are we analyzing here? The 123 manual shows a tee between the vacuum switch in the drivers door and the left rear door actuator.

Sorry, 85 300td. It's actually a 'Y' right in front of the driver's seat with one side heading over to the right side and the other going to the left rear door.
I'm thinking it's probably a solid plastic line all the way to the actuator from that point, but I'm not sure. The line won't hold any vacuum at all, which means it's disconnected from a fitting or has a big cut in it.
