Problem with punch 4X4 on 2003 1500

I bought this Sub used a few months ago and everything checked out at the time. Now where the 2 high, 4 high, 4 low or Auto push button lights are not working and won't shift. It is in 2 high right now, so still driveable but the light next to the 2 high is not lit (as none of them are lit). When I push an of ther other buttons to transfer it into 4 wheel drive, nothing happens. Any quick cure before taking it into a mechanic?

I had a 2000 silverado that would not go into 4 wheel drive. Local shop told me that a servo was bad. $400. I took the switch out of the dash and looked at the soldered joints on the inside. Resoldered a couple and everything worked fine.

Welcome to AF.
You will need a transfer case/transmission capable scanner to check it out and get codes.
Post back code no.
