[jons87mj]

hi i was wondering what should my vacuum presser be at idle ?

i have a 4.0 aw4 np231 and when i engage my 4wd it goes in and my 4wd light does not come on

the light bulb is good and the switch is good and i replaced most of my rubber vacuum lines with new

plz help

are you still running the CAD in the front axle?

Vacuum pressure=15 to 22 is operating range. 17 is considered norm.

Yes I'm still running the CAD

and my pressser is about 15 :dunno:

thanks jon

I would bypass the CAD permanently and ignore the light. :thumbsup:

A presser operates an iron, and pressure blows the steam out of it.
