Ran an air line direct from the pump to the drivers door...........wait for it.......success! All locks functioning, pump just barely runs. Instant lock and unlock.
Conclusion, I have a leaking bad line running from the pump to the drivers door. Now will try and track down where the leak is. It is not in the door or the door pillar.
If I cant find it, I'll just run a new line.
blue test line running directly to drivers door
I take it that the blue line is urethane, the yellow lines are PVC and get brittle. Replace with urethane, you have to abandon most of the yellow line in place as it is wrapped in the wiring loom. The flex point in the rubber conduit between the door and A pillar is the usual point of fracture.
Good luck.
