[QUOTE="rschap1, post: 1832996, member: 60507"] One thing that got me curious... Does the solenoid open up and allow vacuum past to the IWEs for a short time (like a few seconds at start up in 2WD) and then close off with the check valve holding the vacuum and IWEs open? OR Is it a constant draw as long as engine is running and 2WD activated? Most of the diagrams of the system I see show check valves upstream of the solenoid, so I don't think my idea of opening for a few seconds is correct, but I started wondering. (and that is where trouble usually starts) :) [/QUOTE]
