Hello There Folks.
I have a 1990 Chevy Cheyenne 1500 1/2 Ton P/U Truck. It used to belong to my father intill he bought a new car. Now the truck had been sitting for about 2 & 1/2 years till recently. I installed a new battery and the truck started up just fine. But I found out soon that the speedometer was stuck at the 20 K/M mark. I thought it was a simple matter off taking the dash apart and unplugging the speedometer and moving the little wheel back to the zero mark. But this has not solved the problem. Somebody said it might be the Speed Sensor how would I be able to check this? Im just average joe so if someone could help me out I would be greatful.
