Here"s what I"ve learned so much trying to acquire mine to work. The vacuum canister under the battery box only engages when in 4 lo. It is for additional traction as soon as in sand or pulling steep hills. In 4 hi it should not be involved at all. The line goes come a vacuum switch and on some vehicles is situated on the firewall. Mine 96 doesn"t have actually it there, however. Girlfriend should be able to remove the rubber hose (pull straight down) Then view if the cable moves openly by pushing the rubber part in and out. It have to be feather loaded and move through itself into the extended position. (this is the UNLOCKED position)
there is a vacuum solenoid valve increase by the firewall, it might be that.didnt watch the last post sorry, however I did incorporate the factory manual location

I was reading through the business manual, however it did not give diagnostic info. I think it is a switch, for this reason it"s most likely the culprit.

Just got ago from my neighborhood transmission shop. I was wrong saying the vacuum canister just engages in 4 lo. (I"ll need to reread my owners manual.) mine Jimmy is still grounding in 4 hi however the technology at the shop disconnected the vacuum hose at the tee up the heat a few feet and plugged the hose through a golf tee. This disconnected the front axle native the drive line. The transfer case is quiet engaged yet is no driving the front axle. Need to drive to Detroit tomorrow and also he said this will al least obtain me under the road with no damage but my fuel mileage will suffer. Once I have more time, will certainly out her right into the shop because that repairs. He believes that the "motor" is frozen, providing the signal that is stuck in 4wd, thus, not releasing the vacuum top top the canister.

Are you certain the transfer situation is still involved with it in 2HI? seize the prior driveshaft and shot to revolve it to be sure. If it is free, your problem can be the vacuum switch on the transfer case that activates the actuator. 98 3-button setups have a move on the transfer case. Cheapest point to try. Look in the HELP! ar of Autozone. Replace it and cycle that through all of the settings (but wait about 10 seconds in between shifts). If it works, you could have simply solved her problem.If that is locked (or friend can"t acquire it right into 2HI), it might be her encoder on the transfer case (likely) or the computer (less likely, yet common). Also check the ATC fuse under the hood. I once obtained it stuck in 4WD and also it to be the ATC fuse. GM dealer put a 10A rather of a 20A to try to defraud me. Also shot pulling the 4WD fuse for around 10 secs to reset the system. If that works, that is electric (TCCM (computer) or the encoder). If that is engaged, in 2HI and the encoder is functioning (going v all the settings properly), you might be looking at an inner transfer instance problem.
