Today I installed a new stereo in my 2004 Chevy Cavalier. However, when he finished, the installer told me that Chevy Cavaliers tend to have problems with the odometer lighting when stereos are replaced. He would've fixed the problem, but instead I took a $100 discount and told him I'd fix it on my own. He said that all I would need to do is replace the odometer cluster. How would I go about doing that? Where could I buy the cluster? How do I remove the dashboard and install the cluster? Thank you for your help.
