I just bought a 1996 C1500 4x4 single cab short bed with a 305 and 700R4 in it. Have a few questions about it. 1: The ABS light is on and stays on about 80% of the time. The truck stops fine and has fluid in it. I assume the light is due to a faulty sensor or loose wire. Im just wondering if this is a common issue with these trucks. 2: Did these trucks come with keyless entry? I didnt get a FOB with the truck and the man only had 1 key for it and it is a copy not original. If they came with FOBs which type is correct for the model and how hard is it to program a new one to the truck?
