I know this is in the wrong place but please leave as i need to get the most number of people looking at it and hense the best chance of getting an answer.

I have a problem with an Auto dipping rear view mirror. How they work is they have two sensors front and back that detect a change in light and then blacken the mirror to reduce glare.

Well this one now looks like a fish tank with little bubbles coming up from the bottom. I assume these mirrors are fill with some sort of liquid. Does anyone have experience with this type of thing and can tell me what has gone wrong or what to expect when it finally stops changing state?

Between the legal jargon you will find some hints; an electrochromic device. I suspect bubbles suggest impact damage or organic virus and the need for a new one.

Search in Google or a similar search engine for electrochromic mirror and you will also find hints on repair and dissassembly.
