The heated mirror I wouldn't know until winter LOL the other one I'm scared to turn on until I figure out what it is I don't want to find out the hard way LOL

I did a 'search for Copied image' on the Chromw browser and got nothing. Thought I was gonna be so clever. I'm sure somebody in this forum will be able to help you. The best suggestion I can make is to do a search for the online manual for whatever that is from.
I thought my husband could probably figure it out, But he was stumped, too.

Looks like "Mirror heat"
