[QUOTE="dlbleak, post: 3238668, member: 6795"] my 06 z71 shows the ‘service 4wd’ message. Almost all of the info on the web and YouTube is info for the co327 code. I already replaced the push button component on the dash with no luck. I’ve seen videos where the guy replaced all four components and it still ended up being a short though. Has anyone gotten the 321 code and what was your fix? Thanks [/QUOTE]
