I need some help. I just bought an '03 Seville and the driver side mirror had that brown cloudly looking stuff going on. The mirror moves and adjusts perfectly fine it's just that it looks awful and the black plastic around it is cracked in a few places which makes me think it may have been hit and the stuff started leaking out. Luckily I was able to find just the glass on Ebay for $25. My question is just how easy it is to pop the glass that is in there out out with the plastic and pop the new one right back in it's place. Seems like it should be pretty easy, but from what I read nothing is ever really easy with these Caddies.
