add heated sideview mirrors to 2004 impala?

I think one of the biggest things I'm going to miss from my Aurora (that I just sold to get the Impala) is the heated sideview mirrors. Is there anyway to add this to a car that doesn't have it? My old Aurora, when the rear defrosters turn on, it also turned on the defrosters for the sideview mirrors. (By the way, I sold my Aurora because that car had more problems than imaginable. I paid $5,000 for it and put over $8,000 in repairs in it.) But I loved the sideview mirror heater feature.

this isnt gonna help, but the side mirrors on my impala have never needed a "heater"

Well it works really nice when your side mirrors are all iced up in the winter. It makes them perfectly deiced in a few minutes.
