Rear window defogger

[X5sapphireblack]

I turned on the rear window defogger this morning and it does not work. I had my 2010 35d for a month now and 1st time I turned on the defogger. The light on the button lights up but it does not clear up the inside of the window condensation. Am I doing something wrong ? Don't want to go to the dealer for an appointment just yet.

Could be a bad or loose connection. Have you tried touching the glass after you switched it on to see if you could feel the warmth from the elements? I have had mine for about 2 months and the defogger works just like my other cars.
