My son got his 99 chevey silverado stuck in the snow. After he was pulled out the 4wd would not disengage. After it warmed up and we got all the snow pack out from underneath it disengaged but now will no longer go back into 4wd. What would be the first thing to look at?

I have a 1999 silverado with the autotrac system. For the last year my 4wd hasn't been working all except for the auto 4wd. That works just fine but the 4hi and 4lo don't work, only the back ones spin. You can hear both the encoder motor and the actuator work. I was told that the 4wd transfer case control module was the culpret. Can this be re-programed by the dealership or does the whole thing have to be replaced? Also, where is this located on the truck.
