I have a 1992 chevy silverado k1500 and the 4 wheel drive works, but sometimes it doesn't engage. I didn't know if this could be an electrical problem, because it is intermitent.
Do you
have the same problem?

There is a front differential actuator that is most likely failing. 95 percent of the time I find that this actuator is the problem with this 4wd not working. You can check it by putting it in 4wd and check the 2 wire connector with a test light, if it lights when you go across the 2 wires with the test light then you know for sure that its bad. Get back to me if you need further assistance
