[s-cars] central locking system pump

[stefan13@att.net]

Thanks for your replies. I took out the back seat and found the pump, located hidden next to the battery.  The main vacuum line from the pump leads to a manifold of sorts.  My assumption was that each of the five lines connects to one of the doors and the rear hatch.  So I locked and unlocked the car five different times, each time with one of the five lines pinched shut.  Voila - it was the line to the rear hatch, which when pinched made everything work perfectly. Once I knew the hatch was the problem, I could actually hear a hissing sound coming from that actuator.  Turns out, the rubber boot on the actuator which seals the cylinder has a pinhole.  I doubt this part is separately obtainable.  Thanks again.
