Bringing her back from the dead! 7 years! But yes, it will will work..but the mileage is stored in the cluster, you'll have to have the new one programmed to match...look into a company called Specmo for that.
Yes, all 2003 to 2007 clusters are plug-n-play between each other. However, you must realize that the mileage follows the cluster.
So make sure that you buy a cluster that closes matches your car's mileage. A little over or under, whoopie due. But if the mileage is hugely different, you can have it programed by http://www.specmo.com
It is true that mileage is not stored anywhere other than the instrument cluster. It is a easy swap and instructions can be found on this site. Instead of sending mine out for mileage calibration, I simply ordered one that had slightly higher mileage than my original and once I reach the mileage of the new one, I will be swapping them out. Save myself $100!
