1997 K2500 no 4hi

[awcforever]

So long story short I can’t get 4hi to work. 4lo does work. The other thing is when I’m driving down the road, towing or not, the 2hi stays lit as it should but 4hi flickers constantly. If I push 2hi it will stop flickering but it will start again with time. Not sure what’s going on. I suspected the front actuator at first but threw that out since 4lo engages. Any insight?

Thanks

Not sure if you fixed it but this might help you, seems like your problem is the pushbutton switch itself
