    :realmad: I have an 1989 k 1500 w/350 v8, 350Th auto transmission 4 WD indicator does not come on and front end does not engage, fuse is good. I have had this truck for over 10 years and this just happened about a month ago and I have not been able to find the problem.

    Get a buddy to lay down under the front and see if he hears the actuator working when you pull it in 4 wheel, if not replace it, if he can hear it run then take it out and stick a nice size screw driver in the hole and work it until it moves back and forth, my actuator was good put the dang thing was stuck and would not engage all the way in,:gunsfiring:
