overhead display console

I have a 2000 Monte Carlo SS. I love the car, its a blast to drive:naughty: .I had to have the windshield replaced. Now my mirror is too high and my overhead display console(displays outside temp, fuel milage etc...) no longer displays correctly:disappoin and my fuel gauge shows above full all the time:banghead: . Can anyone please help me with this? Any information would be GREAT!!!!

I think the only way to get back to it displaying correctly is by taking it to the dealership

pegged gauges are usually idicators of short to ground.
