Faulty Pneumatic Door Lock System on 4KCSQ

IIRC there's only one vac line to each door solenoid. I think your switch in the driver's door is bad, thus it's not recognizing that you've unlocked the drivers' door and not telling the vac pump to engage.

Although all of the other doors on my '86 4KCSQ lock when I lock the
driver's door with the key or by pressing the lock button on the door, none
of the other doors un-lock when I use the key to lock the driver's door or
when I lift the lock button to un-lock the driver's door.
Can someone please direct me to the location of the "source" of vacuum for
the un-lock "circuit" on the doors?
I expect I've got a failure (Read: leak) somewhere before the master vacuum
line branches to the individual doors.
Are my thoughts anywhere close to accurate???
Thanks in advance for your advice!
