Will not shift into 4 low. I push the botton it flashes and you hear it try to shift at the transfer case then it clunks again and goes back to 2 wh high. Service 4 wheel drive light comes on randomly. When service 4wh light is on it will not shift to any 4wh dr. And the indicator light does not show what drive mode it is in. I think it may be wiring connectors or bad ground as I had the transfer case out resently when I overhauled the transmission.
