Electric wing mirrors not working

So both wing mirrors have stopped working both in the motorised adjustment and the heating function. I have had a look through the manual and cant see which fuse they are on. Does anyone know which fuse it is to save me a job of going through every fuse to see if anything has blown. If its not the fuse are the multi function switches known to break? I had a gold a few years ago and this was a common fault. As far as I know everything else is working as it should.
