Why don't you just do what I used to do when I was a professional steering wheel holder...turn them on when you need them (dew/fog from sitting allnight) or just slightly in advance if you can see the apporaching rain. In the winter I used to leave the heated mirrors on all the time just because running down the interstate I'd run through different "pockets" of air temps and it would play havoc with the mirrors if I didn't have the pre-heated. Just a thought. Can't say I've ever cooked them...but then I'm talking about Class 8 trucks, so their mirror heater elements might be built a little better than Ford's version.

from the 07 superduty owners guide...
could cause damage to the glass and mirrors.
i agree, it would be nice to be able to control them with an aux switch.
Heated outside mirrors (if equipped)
The main mirror glass is heated automatically to remove ice, mist and
fog and activates when the vehicle is started.
Note: The mirrors may be hot to the touch but will not burn. This is a
normal condition.
Type AThe mirror heating elements are
designed to operate regardless of
the geographic location of the
vehicle. There is no switch to turn
on, or other operator involvement
required other than to start the
vehicle.

Type BThe spotter mirror, below the main
mirror, is not heated and must be
adjusted manually.
adjusted manually.
Do not remove ice from the mirrors with a scraper or attempt toreadjust the mirror glass if it is frozen in place. These actions
could cause damage to the glass and mirrors.

The mirrors are great when it's below freezing, but a bit of a pain in the butt when it is wet out. The water drops evaporate and leave spots on the mirrors. You'll see me cleaning the mirrors off at just about every fuel stop.
Routing the power thru an upfitter switch would be a good idea.

i did mine some a long time ago. the mirrors are on ALL of the time. the two drawbacks to this are that obviously your heating elements are not going to last as long, and when the mirrors get wet they get more water spots on them. the easiest way to do it, and as i did, is to select which upfitter you want to use. remove the fuse for the heated mirror from the panel. i believe it was #39. check your manual(it's listed). then, run a 12 or 14 gauge wire from the upfitter wire into the fuse box, and connect it to the upper part of the fuse slot. i fashioned a little plug out of a regular male spade electrical connector to make it fit right. bingo. in about 15 minutes you have switched heated mirrors. you'll know if you did it correctly, as the mirrors get quite hot when they're on. let me know how it goes!

I guess I'm just lucky. After I read this I went out and looked at my mirrors. There are no water spots on them. I know that I use a chamois on the truck after I wash it to reduce water spots but it's rained since the last wash (and I drove through that rain) and I still don't have water spots on the mirrors.

Fuse
Would it be a good idea to place the fuse that was removed from the panel into an in line fuse holder? May prevent burning out the the heaters if a problem arises when powered with the upfitter switch?
