Hello guys, I have an appeal to all of your collective experience. I have an issue with my '99 K2500 (cross-over year truck. Think '98 GMT400). The 4 wheel drive switch only works when it feels like it. Often there are no lights at all. Sometimes it won't even operate the 4-wheel drive. Sometimes everything works and all of the applicable lights work correctly. I have a general knowledge of the components of this system. Just wondering if any of you out there have seen this and can suggest which component is on the blink? This past winter I notices this. It usually operated after a couple of tries but the lights wouldn't stay lit. Yesterday at a sandy river beach I was thinking of using 4 high as a precaution to not get stuck and I couldn't get anything. I was 2 hours from home and when I tried at home the transfer case engaged into all three ratios but the lights wouldn't stay on. is this the dash switch?
