HELP 4X4 problem!!!
I high centered my 99 Suburban due to the snow here tonight. Anyway, I got the rear axle hung up on the pass side. I put the truck into Lo4 and managed to get out. The problem I have now is that it doesn't want to come out of Low. I have tried Hi4 Auto4 and 2 and every time the option I selected would "blink" for a while, then turn itself off. I tried switching while in park and while driving. I also tried disconnecting the battery with no success.
Obviously I have no experience with this and I don't have an owner's manual to help figure this out. Do you guys think I broke something or what?

If it's like my 2005 Silverado, it has to be in neutral to shift in and out of 4lo.

Is this a manual or electronic transfer case?
If your '99 is the same as my '96 Tahoe (I think they are?) You don't actually have to be in neutral to shift out of 4Lo (atleast with my manual transfer case), but if the transfer case has some wear on it, it will help.
Try this, get the truck rolling in drive about 3mph or so, shift the tranny to neutral, and then try to shift the tranfer case (while the truck is still rolling) into 2wd or 4hi.
This may only work if the truck is a manual TC.

If you try everything they mention above and it still doesnt work, get under your truck and make sure you didnt bend any linkages or cables. Since you bottomed out (high centered) you could have bent something. That is doubtful.
You could also try backing up a few feet after you put it in 2wd to see if the 4wd disengages just like Vince said.Adam_______Offical Car Name "ILLUSION"

THANKS GUYS!!
I feel dumb for asking such a simple question, but I was worried I may have broken something. I put it in neutral and made the switch, everything worked correctly.
I'm still probably going to get under it and have a look, once the snow melts! I guess I need to get on eBay and find an owners manual now...

GM has had problems with the transfer case control modules as well. If its not just operator error, take it to a dealership and they should fix it under a GM service bulletin.
