1996 JIMMY / 4 WHEEL DR DOESN'T ENGAGE but LIGHT TURNS ON

My problem is strange... My four wheel drive light turns on for both high and low in my 1996 GMC JIMMY, but nothing engages! In fact, only one tire pushes the car at all times and the rest just roll along.

How do I troubleshoot?

Could it be as simple as a fuse?

    I have the same problem! It worked before and then I had to put a new engine in it and it hasn't worked since.

    Changed engine, now 4 wheel will not engage. 4 hi and 4 low lights come on, you can hear the acuator selecting your option ( i assume thats what the noise is). hope to find assistance here. or can someone direct me to a web site that has a 4x4 1996 gmc jimmy troubleshooting manual, that i can purchase.

The problem is in the transfer case. My mechanic said there is a pin that engages the 4x4. My pin sheared off. He replaced it. It works fine now.

My 1995 GMC Jimmy won't let me switch into four wheel drive. I had in this morning in 4 wheel low, but when I went to put it into high nothing. Now it feels like the button is stuck, none of the lights...


there is a "modulator " on the transfer case with a 3-4 pin plug that fails often.this may be defective as well as the relay component that turns it on(rwhich is located under the battery)...try cheching/changing these first....the "modulator" is about 30 bucks and the relay is about the same

I have a 2000 GMC jimmy the service four wheel drive light is on I was told it was the four drive buttons were bad switch them out and still has service four wheel drive.


The transfer case may be low on fluid. I know from experience that if the level is too low or too bad the light comes on. Either way I would have it serviced.

I own a 1995 GMC Jimmy and I dont know if my 4wd works or not the light does not turn on when i push the button i do i know if it works or not? does it need to be in park or neutral to ingage?


You can shift into and out of 4wd hi in any gear even when vehicle is moving. You must stop and put in neutral to shift into or out of 4wd low.
To see if it is working, go to a dirt field or on the beach if one is available. Put truck in four wheel drive, turn steering wheel all the way one way or the other and stick you head out the driver window and look at the front tire and "PUNCH IT". If the four wheel drive is working you will see the front tire spin. Hope this helps.

I had a similar problem, only it would not engage. I had my mechanic look at it. He said that there is a pin that when a lever is moved the pin engages the 4x4. My pin sheared off. He replaced it and now it works great.

Four wheel won't engage


Theres a vacume dash pot under the battery box. It pulls a cable that engages the front diff. Put the vacume line and you'll have lights and four wheel drive. (it happened to my blazzer)
