Right, first off im sure it wasnt there before i changed my drivers side mirror (thanks to some little chav kids kicking it like a football in the middle of the night and scratching all the paintwork too).
Now i know theres one on the passenger side for the thermometer or something but now ive got one on the other side, and its like a switch that you can have in two different positions but looks identical to the other side.
Anyone know what this is?!
