    Hey guys...

    My 2005 Blazer seems to have an intermittent short/open somewhere certain parts of the instrument cluster will black out randomly. Whacking the top of the dash behind the steering wheel brings it back to life.

    I noticed recently that the odometer is not increasing at all. The trip meter works but resets back to like 2.3mi when you shut the truck off.

    The speedometer works fine.

    Am I to assume that the whole cluster should just be replaced? If I did would the mileage be correct or would it show the mileage of the donor truck?

    I'm getting tired of addressing issues with this truck... :rolleyes:

    A friend of a friend of mine repairs late model dashes & digital clusters on many later model vehicles at the company he works for..

    He has fixed several at my friends shop,he finds cold solder joints often fail after some years pass,it isn't always a faulty resistor,capacitor or diode,but often it is...
