Well I went out to my grand prix today and its December so i'm sure everyone knows its really cold outside. As i opened my car door and got inside I noticed a few cracks in my mirror that weren't there when i left it. The mirror had already lost its dimming abilities because the gel membrane inside has busted from the temperature. However i was still able to use the mirror, but now that its cracked a bunch i need a new one. I had researched into the company that built them for all vehicles not just the grand prix when the dimming feature stopped working the first time. It was a company called dollison and they had gone out of business because of the cheaply built product. I know this is a common issue on the mirror. There was a company out there where you could send your old mirror in and they would send you a refurbished model with a different auto dimming glass system for 75$. I cannot remember who it was or what the website was since i lost that website from the favorites listing on my old computer. If anyone knows what company it is or where i could get a replacement mirror that would hold up better that would be great
