caravan speedometer quit working

2002 caravan. just quit today. I noticed the dash light were flickering but working fine. All other guages work fine. Any ideas??

Patarusky, I'm no expert on the newer models but when my speedometer quit working in my 1993 work van, a Voyager my problem turned out to be a vehicle speed sensor. For your's it could be several things but try this. Hold down the trip/ reset button then turn key to on position, wait until display shows code then release the button.
