Just bought a 2001 s-10 zr-2 pickup... the 4wheel hi button is illuminated on the dash, but only the back wheels spin. I played with the 3 buttons, but it refuses to change at all. Is this a common problem/what could be causing it? Seems like an electrical issue rather than mechanical, but I dont know enough about this truck to say.
