    I have the same problem. It will be in 2hi and switch to 4hi on its own but sometimes I can't get it to go backt o 2hi. Are you finding any solutions?

    I've had the same thing going on with my 2000 jimmy for 2 years now. It used to do it only when we turned a sharp corner or into a parking space. Last year it started doing it going straight on the freeway, usually only in 4hi now it has started going into 4 low. The last time it happened we had to turn off the car and restart to get it back into the normal 2hi. I really hate this vehicle we have had nothing but problems with it a lot of what has already been posted on this list. This is one lemon of a vehicle, I wish it wasn't paid for or I would get rid of it and buy something else. For the time being were stuck with it. One thing is for sure I will never buy a GMC again!

I don't have the owners manual, and have never owned a 4x4 in the past, as stupid as this sounds i don't know the proper procedure to engage 4 wheel drill hi


you have a lever or switch that engages 2wheel normal driving 4 wheel high for wet slippery conditions ,then you have four wheel low for real muddy and deep snow conditions
normally change from 2 wheel to four wheel high on the move .important nearly all 4 wheel drive vehicles must be stopped to engage low otherwise do damage to transmission

1992 explorer automatic hubs.Button in dash does not engage $ whe


I have the same problem with my 92' four liter explorer. I believe it has something to do with the transfer case motor behind the tranny. Under a pinch, I tapped on and around the transfer case
and tf motor, and the four-wheel drive engaged. I suspect it might be from loose wiring or a bad contact of some sort.

Disconnect battery before unpluging and pluging new mudule in. This unit controls the electronic switching between 2 and 4 wheel drive..Wes
