I have a 2002 chevy suburban 1500. My question is about the odometer. I have documented numerous occasions where the actual mileage has reset to a previous marker, along with the trip odometer. For example.I drove 15 miles for some errands and returned home, as I got back in the truck later in the day the mileage had reset to 125879 from 125914. The trip odometer no longer read the 15 miles but was at 1.6. No one used the vehicle and I have had suspicion for some time that the odometer was reading improperly but this is the first time I have documented it. Everything else, including the speedomemeter, works fine, what could this be?

Generally if the speedometer works and the odometer does not, the problem is with the cluster and it is eletrical one.
The instrument cluster must be remove and check resistance at each components

let me know if you have questions

Just wanted one more thing, would I still need to check the cluster even if the odometer never actually turns off? Its always working, never goes blank just resets?
