For the last few weeks my instrument gauges have working intermittently but my speedometer and tachometer always work. The messages unknown driver and service 4 wheel drive always pop up. I put a brand new battery (Diehard Platinum) in it and pulled the IP fuse and disconnected the negative to try and reset something. I also switched the 4 wheel drive in and out several times and it works fine. I also tried wiggling the throttle body wires but that doesn't make the gauges come back to life. I am lost on this one. Somebody please help because I am totally stumped. If there is a Hummer tech in the Dallas/Fort Worth area I will pay them to figure this out. Thanks for any help on this issue.
