I realized my hubs were always engaged so i pulled off the tires, put a vac pump on the iwe's and the both work fine. went up to the check valve, and it seems to be working, plugged both iwe's in, then connected pump vac to top soleniod outlet and pumped it up. Only one Iwe disengages. I unplugged the Iwe that would not disengage and the pump continued to hold pressure. Can these lines clog? If so, would compressed air destroy them? How else can I clear them?

 

I've read on here of a couple guys that found plugged lines up around the checkvalve and solenoid. It sounds like you have a plug between where the lines split to go to either side, and the right IWE. You could try using air, but I'd be careful, those lines are for vacuum, not pressure. The worse you could do is maybe blow a fitting.
I think I'd just replace the line.

 

Thanks, that makes sense. I will have to start finding the disconnect points for the line. It is the passenger side, so its a lot longer. I have been looking for vids on how to take the hose off but I cant find one. I guess when I do it, ill have to make a vid.
