Hello I too had a gauge cluster problem on my 05 coupe. I ended up getting a used one that works great but the mileage is way off 55k on original now 96k on used one. It works fine so I might just leave it the way it is. Dealer wanted a crazy amount of money for a rebuilt one plus I had to leave the car for 2-3 weeks.Hi Fishslayer,
I have bitten the bullet and ordered one from eBay. Just have to wait till it arrives this side of the pond (UK) to see it was the cluster. I thought corvettes were bomb- proof cars where nothing goes wrong. Only had it six weeks and the expense has started.
