Service 4WD light 2000 Silverado

Nov 13, 2005 1 Replies

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..
