When you put it in/out of 4x4, does it actually engage/disengage? I don't know if the light is associated with a code, but it may be worth checking.

I did a little searching and found this:

Since the use of 4WD requires vacuum, a leak, or destruction of the lines can render the 4WD inoperative. However, the lines are fairly well protected, and failures are rare. The vacuum switch is a known weak point. The switch is a little tower on the transfer case with four lines coming from it. The switch is activated by the transfer case when a lever inside the case presses a plunger at the base of the switch. Then, a spring in the switch extends the plunger when the lever is retracted. The problem is that the plunger is rounded to ease the lever's action. This rounded part can be easily jammed inside the switch by the standard gunk in the transfer case. When this happens, the interlock and the 4WD light will not disengage. It is an easy fix by just un screwing the switch and cleaning it, but when it happens, you can feel the extra drag of the front driveshaft and associated parts.

Hope this might help.

Your CAD (center axle disconnect) isint disengaging. Check all the vaccum lines on the disconnect, lines leading from the disconnect to the switch on the transfer case & the lines going from the source to the switch. It can be a real PITA to track down a leak. It also could be the modulator getting too weak to pull the fork.

You might also pull the CAD out of the axle tube & check it out. I recently replaced a leaking CAD housing gasket. While I had the CAD out of the axle tube, I gave it a good cleaning & inspected the fork pads just to be on the safe side.

The transfer case switch is just one weakness in a poorly designed system. The switch that turns on and off the dash indicator is on the CAD itself, so the transfer case switch is not likely to be your problem. More likely is that the CAD is not disengaging or at least not completely. Better solution is to get rid of all the vacuum system and replace it with a Posi-Loc cable-actuated system. Positive engagement/disengagement, 4WD Lo operation and more peace of mind that when the 4WD system is locked/unlocked, it stays there.
