I searched the past threads and can't seem to find anything that quite fits my problem. And it seems that most of the GM trucks with this problem require a gauge cluster replacement (an expense I'd like to avoid) The short version of the problem is about a month ago the speedometer, tach and odometer just quit working. The rest of the gauges seem to be working fine. The engine hours counter in the digital display is working (accumulating) but as I said the odometer and trip meter are frozen. Does anyone know if there is a simple (read inexpensive) solution?
