Front end on 2004 Buick Rainier

I suspect awd stuck on when going slow and try turning on dry pavement front end shudders and vehicle barely moves. both directions. seem to have no others problems when driving. I would guess that this is sensor controlled, or transfer case stuck? Any way to tell for sure?

I had the same thing happen and had to replace the motor that controls the all wheel drive--over $900 at the dealership (only mechanic that could fix it).

Did you find out exactly what was causing this problem? Did you have it repaired? I am having the exact same problem.
