4wd selector back light flickering.

[Gearhead54]

I starter my truck yesterday morning and the back light for 4 auto - 2 high -N - 4low - 4 high and yellow indicating light were flickering. Irregular, pulse to flicker. PRND was normal. It was in 4wd high. I got off my snowy township road and wanted 2wd. It did not work. It wouldn't respond. That was 2 miles from my house. 1 more mile, back light went to normal, steady light and then I pushed 2 high and it worked. Any one else have this issue? I have had numerous issues with my truck. Am/FM quits. Whole screen quits. 2 button reset doesn't work on mine. Back glass started leaking 2 weeks ago. Any modules at rear of cab that might be corroded?

Could be an issue from your rear window leak, but who knows. Could be a frozen actuator on the transfer case and after it warmed up, it was fine. Just some thoughts.
