Prevent heated mirrors turning on every time I start truck?

[Gullzway]

I park my truck in my garage and don't need the heated mirrors/wiper park 98% of the time.
Yet every time I start my truck they come on and I have to turn them off.
I've tried changing from auto to last setting but I believe that's only for remote start, doesn't make a difference anyway.
If I turn off the heated seats and steering wheel, they do not turn on the next time I start my truck. But the heated mirrors turn on every time regardless. Surely you can turn that off?

Has nothing to do with remote start or the heated steering wheel/seats. It's an (undocumented?) feature that Ford has had for over a decade - when it's cold out, the vehicle automatically turns on the rear defroster. It's the same control as the heated mirrors and windshield de-icer, except Maverick doesn't have a rear defroster.

Only unofficial explanations I've seen indicate it's intended to provide extra electrical load to help the engine warm up, though it could simply be an automated assist so you don't have to turn on the rear defroster manually.

Not aware of a way to turn this undocumented feature off; it's never been in the settings menus, but there may be an option in FORScan.

Only drive it in summer. That’ll do it.

Just funning you.

Do not park outside. Mine turn on when it is below 32 where the truck is parked outside.
