2004 Chevy Tahoe V8 Two Wheel Drive Automatic 105650 miles
My speedometer isn't working properly, that is to say when it is very hot outside or after I have been driving for an hour or so, the speedometer stops working normally. By this I mean it either sticks on my current speed and doesn't move no matter what speed I am doing, or it will stick temporarily, then starts to work again so that when I come to a compete stop the speedometer will read anywhere from 10 to 40 mph. When it does this, the only way I can get it back to zero is to repeatedly crank the engine and then turn it off, until the speedometer returns to zero. Early in the mornings when everything is cold it works fine. The remaining gauges(tachometer, battery, coolant, and oil) all work normally no matter what the condition. My question is this. Is my instrument cluster bad or could it be the sensor for the speedometer?
