[3.4 grape of wrath]

I bought a used gauge cluster off e-bay and my plan was to swap it out with my old one but the one I bought was a little beat up. So I removed and swapped the odometer/trip assembly which contains the gears,motor and rotating numbers. It also has a wire connector which plugs into the pc board. The odometer still did not work so then I replaced the pc board. Problem solved. There must be an electronic component that goes over time.
