4wd issues
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.
