Hey guys I have a 96 dodge 2500 w/ the v10. My 4x4 is not working. I have checked the vaccum lines and they are not leaking but I only have vaccum to the switch on top of the t-case. I replaced that switch thinking that would be my issue but I still don't have vaccum to the CAD. Any suggestions?

Not familiar with this system, but just confirming you have vacuum to the switch, but not out, correct?

Assuming the switch should have vacuum passed through when shifting 4wd; I would still assume it is either a switch issue or insufficient vaccum.

Do you know what the vacuum spec is vs what vacuum you are seeing?
