Has anyone experienced a burning smell when turning on their heat first thing in the morning? I get a terrible odor when the temperature is slightly above freezing and end up having to rolldown my windows - counter productive to having the heat on. This only happens after the car has been sitting for a while (8+hours) and usually in the morning. I have brought it into my Acura dealer with no success.

 

I've experienced the same smell I could never figure out what it was.
