ok when the service light is on, 4x4 is stuck engaged.

conveniently, the alternator also died, but i got that handled (or will tmorrow that is)


i removed the battery and tray, the vacuum switch doesn't move when the car is turned on, but it en/disengages freely when manually operated, and i can hear air squishing from the sensor/switch/whatever that is on the firewall right up above and center.

from there i see it tapping into another vacuum line and from there i can't trace it.

i looked around the xfercase, i dont see any vaccuum lines 'cept a suspicious one that attaches on the top out of reach.

where should i be checking exactly? w/o a vacuum schematic i'm kind of lost.
