02 Tahoe. I’m not a mechanic and just looking for some help. When I engage the 4wd, I hear it. But then the service 4wd light comes on and it shifts rough. Auto 4wd stays on if I push it and can only get back to 2 high if I turn off the Tahoe. I’m going to start by replacing the button module. If that doesn’t work I’ll keep going down the list. Any advice on what it could be or what to try? Thanks in advance.

 

Dupe please delete admins.

 

admins won't see that. To report it, hit the yellow exclamation icon on the left side.

 

Sorry I’m still new and trying to figure out how to delete from the new member area

 

Got it! Thanks MMJ.
