there truck go into 4-wheel drive after starting? I started the Truck the other morning and it was about 30 degrees out and after I started it ran inside for a sec. and when I went to pull off it was in 4-wheel high. What yall think it could be?? Thanks..

The encoder motor (in the xfr case) and switch assy on the dash are known to go bad .. encoder motors were a common problem on the 03s .. I would pull the 4WD fuse until you figure it out .. it would be bad to get it stuck in 4WLO or HI when driving on dry pavement
