1996 GMC Jimmy 6 cyl Four Wheel Drive Automatic 56000 miles
the speedometer quits working once headlamps or parking lamps are on, but it is not effected by daytime running lites. So at nite I set cruise control and it works fine but the speedometer does not move. Once you stop for 5 or 10 minutes it will then work fine for another 10 minutes then hand will remain stationary.
