one more thing...stuck in 4x4

when the rotor got really bad my roommate pushed the 4x4 button for no reason and now its stuck in 4x4. Any input???? I have no clue how to get it unstuck.

I know with my moms 2001 Blazer it wouldnt come out of 4X4 either. IT was underwarenty. The electric servo that switchs between 2 and 4 wheel drive was bad. They replaced it and it works great. I heard they get corroded and it looses track where the servo is at. You may try disconnecing the battery from about 5 mins and them reconnect it and see if it will go back to 2 wheel drive.
