i have a 1994 GMC K1500. As far as I know the 4x4 is working because I have locked it in and when I turn my wheels I can feel the front wheels engaged. Although, the issue is the indicator light is not lighting up for some reason. The main light is working on the lever cover but when engaged the front axle isn’t lighting up. I’ve replaced the bulb, checked fuses, replaced the front axle actuator, and the T-case switch on the front of the transfer case. I don’t know what else it could be. I’m not even sure what is responsible for making it light up. There is a white plug hanging from the same harness the actuator wire goes too I’m not sure if that has anything to do with it. This plug is suppose to mount on the front axle. Although I do not know where the receiving part of the plug is. It’s almost as if someone removed it. I just want my indicator light to work. Any suggestions?
