I know there have been many threads on the rearview mirror dying. However, is the mirror computer controlled in any way? I was getting some extra keys made, and they said they were having some difficulty with the computer. When I got the car back 30 mins later, the mirror was dead. The service "techs" said they didn't do a thing to the mirror, but the service manager said he hadn't seen a thing like that happen in teh time he had been there. Also, does the mirror just die, or does the "air bubble" slowly get bigger?
