I have heated mirrors on my 09 XLT but found no switch to turn them on...

Are they automatic, or do they turn on when the rear window defogger is on?

They should be connected to the rear defogger switch. It's how the older models used to work, and it's how I wired my heated mirrors.

Confirmed, mine operate from the rear defrost switch.

While technically correct in "Anything Goes", "Tailgate Chat" would have worked too.

Thanks folks!

Fixed.

I always thought they automatically activated when you started the engine for 15 minutes or so (and if the temperature was below freezing)

If I wanted to install heated mirrors on my XLT, how hard would it be (and how hard would the dent be in my wallet)?

I ordered mine from Muth (they're also signal mirrors) and they cost around $200. The instructions include which lines to tap into for the signals, but they recommend a separately sold switch module for the heated mirrors. Since the defrost system was already designed to handle the load of heated mirrors, I tapped directly into those lines instead. Installation took me about an hour.

That is one option I wish that I had gotten

I don't have that feature, I always have to start my car and turn it on. It's not a "button" so I can't even activate it at night before (remote start baby!!), fortunately it's very effective so it works quickly. I would assume that the car would have to be able to know that it's below freezing??

I looked at the MUTH mirrors, I wanted integrated signals in the mirror, and even with my already wired heated mirrors I just decided it wasn't worth the $200.
