4x4 will not engage in 96 gmc yukon

When you push the 4 high or 4 low button on dash the lights on the button keep flashing and the front differential does not engage into four wheel drive. What should I check to find the problem?

    light flashes in 4x4 hi and low will not engage 4x4

  • Anonymous Jan 04, 2009

    Same deal for me.

  • 96 Yukon Jan 10, 2009

    When I push the 4x4 button the lights flash, I hear the clank when it shifts into gear but yet the front axles do not lock and only one tire spins in the rear. What could be the problem???

  • decepticon Feb 01, 2009

    i have a 1992 jimmy that is doing the same thing and i was woundering if it had anything to do with the vacum accuator indicator switch that is connected to the lagest vacum line that t's off to the accuator. this switch is located on the wheel well on the passenger side by the battery.

  • cconley521 Mar 10, 2009

    I have the same problem...When you first start the vehicle if you put it in neutral it will allow you to put it in 4x4 but for only 10 seconds and when you shut it off it goes out. I know that it is not the actuator switch have had it tested any ideas?

I just fixed a friend of mines 96 yukon...shift to neutral press 4H and u can hear the actuator make noise (we even replaced it with a new one his idea and the same thing happen as old one), so as he hit the switch for 4H i layed under it (on 4 jack stands) and I could hear the motor on the transfer case make a loud noise (well thats working) and before all this I asked him did u check all your fuses (he said guarnteed to be all good) one night it was bothering me so i looked through the owner manual for the yukon and in the fuse box on driver side by the door there are (2) fuse for the 4wheel drive unit,pull one of the fuses good...pulled the other one and it was blown put in a new fuse and it works like brand new..pull fuse for anything that has to do with 4 wheel drive componants,

1996 Yukon 4X4 Electronic Shift on Fly.


I had the same problem with the shift on the fly push-button 4x4 on my 97 Suburban. GM Shop manual indicates that it could be due to an encoder error on the actuator motor. Try pulling the transfer case fuse to reset the transfer case control module. Wait at least one minute. Re-install fuse then re-try operation. Did it last week and that saved me a trip to the dealership and extensive troubleshooting.
