Just stopped working? Was a bit steamed up the other morning when I went to work, so pushed the button to turn it on but got no light to confirm my actions. Repeated and insistent pushing didn't help. I thought the little bulb in the switch might have gone at first but after a few minutes I was still looking through a misty rear screen. Any ideas of where to look?

 

Have you checked the fuse? These heating elements use a fair bit of power. Failing that, dodgy connection somewhere.
