Ok i suspect that the pass front door element is bad. I had everything hooked up and to test it, I unplugged the yellow with a red stripe line to the front pass door and stuck the mighty vac on it. The vac gauge climber and the car shut off and all the doors locked, but when I unlocked the drivers door, the locks didnt go up even though I still had the yellow with red stripe line bypassed. When a vacuum element goes bad will it usually leak into the lock and unlock line, or will it usually leak only 1 way?
