2008 Hummer H2 SUT "Service Four Wheel Drive"
New to this forum. This is my third H2 and my first with the Service Four Wheel Drive in the dash. I have replaced the encoder motor and the switch in the dash and it is still having the problem. Has any one heard of a bulletin to reprogram the computer that can fix this? The truck only has 33,000 miles and I doubt it has ever been off road. Any suggestions?
