Once again my truck has no gauges, we have tried cleaning the connections on the back of the speedo, no dice, checked all the grounds, no dice, got new cluster, no dice, finally broke down and spent 700 bucks for a new compter... the one on the firewall. that worked for 3 days, now its back to the same thing. Check engine light comes on and says no bus in the odometer. I'm at my ends wit with this truck since i just recently bought it, i have only driven it 250 miles in 2 months because of this prob. BTW the truck is a 2000 3/4 diesel. Any ideas would be much appreciated.
