99 silverado 4x4 problem..?
turn key to on, you can hear the relay in the dash click on and off several times. The light indicator to let you know if your in 2 or 4 wheel drive stays in 4hi. If you hit 2hi, auto, or 4lo the light blinks on that button then stays solid on 4hi. My service 4wd light did come on, but went back out. And even though it says 4hi, the truck is in 2 wheel. Its snowing out so I gotta get this fixed asap. Thank you very much..

You could start trowing parts at it or take it somewhere that has a scan tool that can read the 4x4 system. It could be a simple sensor issue but it also could be something broken in the transfer case. The key is the service light was on so there will be a code that should narrow down the possible problems.
