Shoot me your VIN. The last 8 should do it. It'll be tomorrow sometime though.
Just to make sure, you are talking about the switch assy on the dash? Or the actual 4wd control module?
i havent tried any where else yet, but im going to call jims junk yard here in frankfort, but i need a new 4wd switch module, mine is steadily getting worse. i have a 2000 silverado ls w/ the 5.3l v8 with the auto 4wd option. i can replace it no problem, i just need the part. if you could shoot me a price, i would be greatly appreciative.
