In chasing down PO's wonderfull !@!$!#!:
Driver's door does not have a vacuum line in the door and needless to say, a vacuum line is NOT connected to the lock. Acording to the CD manual, there is a three way vacuum connector under driver's floor mat connectiing vacuum to the pass. ft. door and driver's side rear door.
?Is this connector under the center of floor, black plastic air duct? If not, where? Often illistrations in manuals are rather creative.
10 extra points for naming the PO in TX.

Disclaimer: Dear officials, I do not intend to do any harm or hire any one to harm anyone who may have previously owned a car now owned by me ... but I do have a very large and hungry dog & if that is not enough there's the old lady!

May you go to heaven and watch PO's drive Russian 2 cycle things that look like cars.
