No corrosion. Last night I disconnected the battery and touched the cables together per direction from another site. Now the it seems as if it is stuck in 4HI, the light on the switch flashes. If I push any of the buttons that button will flash a half dozen or so times then go back to 4HI. I can hear the axle actuator when I push the button...but that seems like the only thing that is happening. So does this sound like tccm, encoder, or actuator?
