First let me start by saying i have a 1994 k1500 pickup with the floor type 4x4 selection. I went to put it in four wheel drive and the light came on but no power went to the front wheels. I did some research and I now know that the actuators are known to go bad. But everything i've read said that the 4x4 light would not come on and mine comes on sometimes. Today i was driving and the light was going on and off. Does this sound like the actuator has gone bad or could it be something else. Thanks in advance.
