Weird. I guess the Heater/AC vacuum line is 'upstream' of the 4x4 solenoid one. I would backtrack from the AC/Heater unit then because it sounds like thats where the problem is because other vacuum systems still seem to work.

Good luck!

Ok I have same issue tested each hub the right held vacuum and the left wouldn't hold vacuum. So to fix it are their seals that can be replaced or do I have to get a whole new hub?

Did you check your hose going to that hub? That's where mine was leaking.

Yes I hooked up a vacuum hand pump right onto the hub fitting

Well, if you hooked it up right to the hub and it's still leaking, that would be something in the hub.

Start with cleaning the hubs. Seals can be replaced. Link should have the part #.

This may be a repeat but mine had problems and was not going into 4x4 "Under warranty lol "Great dealer Btw" and it was an actuator...they replaced it and it works flawlessly
