41chevy Posted May 23, 2015 Share Posted May 23, 2015 The Speedometer, Odometer and Trip Odometer all get their info from the speed sensor. If the Speedometer works and the rest don't, than more than likely the Odometer/Trip Odometer module in the gauge is bad.

Timmyb Posted May 23, 2015 Share Posted May 23, 2015 So is it a digital odometer? In my kw, my odometer was blinking on and off. I found a new odometer display on eBay to fix it. Not sure if you could do the same for yours.

I've seen the odometers spin when stopped adding 50 or more miles at at rest. Ain't electronics grand?

MackMack613 Posted June 14, 2015 Share Posted June 14, 2015 Might check your wires coming off the computer. My ch speedo/odometer quit working and checked the wires and someone had just twisted wires together and taped it and come undone. New connector works fine Quote Link to comment https://www.bigmacktrucks.com/topic/40120-speedo-fine-but-no-odometer/#findComment-293300 Share on other sites More sharing options...
