I have a 01 blazer zr2 and it won't shift out of 4x4 .. The 2wd light and the auto 4wd light are both on but it's in 4x4 what would most likely be the problem ?

 

Position sensor in the 4x4 encoder motor. But need to test with a tech2 scanner (dealer) to know for certain.

 

If I pull the atc fuse I will have 2wd .. I found this out when I went to leave a stop sign this morning on my way to work and went sideways on wet pavement lol
