4x4 will not disengage from four high

[yaterman8]

To start off i have a 99 powerstroke with the 4x4 turn knob on the dash....So i decided to head over east this weekend and the passes were packed with snow so i pulled over and turned the knob into four high got back on the road and it did great got to my brothers house and didnt drive it for a few days got back into it today and turned the knob back to 2wd and nothing the light is still on in the dash, tried everything neutral, reverse, park, everything and it still wuld not come out, So i had to drive it 100 miles back home in 4 high...So my question to all of you is where do i start i am not familiar with all this electronic four wheel stuff!

Thanks
Rick

update...Crawled under there and unplugged both plugs from transfer case hooked them back up and seems to have put it back into 2wd the light in the dash is off now

no clue maybe your connectors had crap in em try cleaning them off good with contact cleaner and then put em back together and check it

Ya it was weird it would go from 4 high to 4 low just fine but not 4 high to 2wd

ok so decided to check things out again its still stuck in 4x4, so i took the motor off and turned the shaft with some pliers until i got it back into 2wd, So i am thinking it may be the motor but not sure any suggestions would be great

I had problems with the switch in my cab no catching properly, almost like it was stripped. But you can pull the switch off and make sure the metal rod is actually moving...I've had to use pliers before to get it to disengage.

Thats a good idea, do you have to take the switch apart to see if its working right?

The nob slides off, and for some reason after pulling mine on and off it works now. I just have to make sure I put some inward pressure on the nob when turning for it to catch on the metal splines. Hope that helps..

i have had it out of the dash before but never did figure out how to pull the knob off of it?

I had the exact oppostie problem. Mine wouldnt go into 4x4 at all, but it would get it out. It turned out to be a valve/ selonoid(sp?) for the 4x4 was stuck so that was $74. Its the one on the passenger side beside the vac, pump. Hope it helps. Maybe your valve just lets it lock, not unlock?
