Service 4WD light 2000 Silverado

I have a 2000 Silverado with push button 4 wheel drive selection.

Twice now the service 4WD light has come on, and I am unable to shift from

2wd to 4wd or auto 4wd. Problem went away both times after one or 2 restarts.

I have scanned for codes a few days later and there are none. Shouldn't codes be stored in memory for a while?

Any ideas what the problem might be?

Thanks in advance!

Very, very common problem.....

Cold solder joints on your dash 4x4 push buttons....

Replace push button module for $50 or resolder..

I had that prob in my 2000 5.3 Ext Z-71 2 years ago..
