I have been trying to diagnose and repair my vacuume system. I am sure I have a vacuume leak somewhere. My HVAC system works like it should. ( heater/ ac controls )
I cant find a post that describes the complete system for the hubs. I cant find the specs for the vacuume pump or how the system is suppose to work.
I.E. vacuume pressure? How to service all the seals?
I get vacuume to the hub when I turn the knob, but the vacuume only lasts for a short time. The pump cycles.
I have not put a hand pump (with gauge ) on the hub its self yet to see if its holding.
I would like to know and see a document on the system.
