My "4 wheel drive" light stays on all the time, on my '84 k5. One day it just popped on and hasnt went off since. It is not in 4 wheel drive. I just had my transfer case fixed and it still stays on. /forums/images/graemlins/1zhelp.gif What could it be? Has anyone had the same problem? I know these r old vehicles and things like this happen. If there is a sensor or something like that somwhere, where is it? Any help please!!!
