Hello all. Have a little problem with the rautodimming ear view mirror in my 2001 V70XC. It doesn't work too well or too fast. My wife has a Acura TSX and the mirror in that car changes within 2 to 4 seconds of it sensing light from behind. My Volvo's take almost 30secs to 1 min before it changes. 1. Is there a way to diagnose the mirror separately? 2. Is there a sensor to be replaced? 3. Can I get a replacement mirror and install it my self? 4. How much (app.) would a new one cost from Volvo? Thanks all for the help. GGO in NYC.
