Question about auto 4wd on my 99 GMC Jimmy

When I manually engage the auto 4wd on my 99 GMC Jimmy it begins to flash for approximately 30 seconds in auto 4wd. After 30 seconds light switches to 2hi. Is that the normal operation on how the auto 4wd is designed to work.

4wd 2001 gmc jimmy will not engage


it is possible one of the auto lock hubs is not engaging properly, look in your owners manual and trouble shoot with that but sounds like for some reason it will not engage in 4 wheel drive, sometimes the button is the problem, I am not a fan of the push button system gm has, and I prefer to engage the transfer case with the tried and true second gearshift in the middle of the floor good luck

My 2000 gmc jimmy is stuck in either auto 4wd or 4wd hi, it won't go back into 2wd hi, the service 4wd light is lit on the dash, would you have any idea what the problem might be and how much it would cost...


Use the Owner's Manual to manually go into neutral and reset to 2WD HI. But then look under the hood check the fuses or look for wiring that may have come unplugged.
