I have a 97 Yukon 4x4 with push button 4wd. At random times I will look down at the indicator light for 2wd and it will not be lit. sometimes I can push the button and it will light up but not usually. When it is not lit it drives like it is still in 2wd and does not seem to have changed. I have not been able to see if it does it in auto, 4Hi or 4Low because I mainly drive in 2wd. Was wondering if anyone else has had any issue like this and what may cause it? Any help is appreciated.

Mine does the same thing... Lite will be on after you fiddle with the button some but will not stay on continuously like it should. It does this in 2wd and 2wd Auto. I don't really use 4wd for long so not sure if it happens there too. I don't think its shifting on its own more like the ground for the lighted part of the switch is bad so I think it stays in the range you have selected but just the indicator lamp is not "on". I plan to replace the switch one of these days to see if that fixes it.

I just took the switch out of the dash and made sure all the connections were tight. Put it back together and everything seems good now
