Switching back into 2 Wheel High from 4 Wheel Low
Bought a 2006 GMC Envoy... It was in 4Low and I
don't know how to get it into 2High. When I put it in
Neu. And turn knob, it blinks above 2H but lights
up above 4H and stays lit there. It has an "auto"
light between 2H and 4H, do I just leave it there or
get it to stay in 2H?
