Heated Mirrors

[DarkBluePSD]

Hey Guys,

I bought my F250 about a year and a half ago. I noticed the mirrors have a indicator on them that I believe lights up when they are on.

Is this true? I have never seen them light up. Can they be working?

Please help.

Thanks in Advance.

If you are talking about the little heat symbol on the mirror itself, it doesn't light up. It is just letting you know that you have heated mirrors. And just FYI the mirrors on our trucks are heated non stop even in summertime as long as the truck is running..you can run them to an upfitter switch to be able to only turn the heat on when you want.

Really?!?! Why the hell would Ford do that?

I have no idea..you would think they would have it to where it only turns on with the defroster on but who knows..next time you have been runing your truck for a bit feel the glass and it will be warm...I'm am going to reroute mine eventually.

If you want to put a switch in for your heated mirrors:

I installed a heated mirror switch - Ford Truck Enthusiasts Forums

Yeah, I diddnt understand why they did that. My 2010 has a switch to turn them on/off

they do not stay on all the time , the come on when first started and temps bellow 32 , after that they shut off above 32 and it cycles.

So, if I leave my switch on, the light on my switch will turn off when the truck tells it to turn the heat off? Cause basically my switch is just in-line with the power to the mirrors.

Haha you are more than welcome to feel mine...here in sunny california 90+ weather mine are on all the time. My buddy has an 07 that do that exact same thing so I would say that is a little more than coincidence.


If what you are saying is the case then why would people be running them to separate switches?

Not arguing with you but giving you two known examples..and I have read it from others on here
