Driver side mirror always fogged up?

You may want to contact GM and get a copy of your build sheet. I didn't know my mirrors were heated either until I read my copy! It certainly isn't obvious! I suspect it is a pretty standard option.

I'm not 100% sure but unless it's a manual mirror from a work truck, it has heat. All DL8 mirrors are heated.

 

Quickest way to verify is look in your glovebox for the dl8 RPO code or move the glass to the side and look for the 2 wires attached to the back for heat.

Well I guess there are heated mirrors fellas, turned on the rear heat and the passenger mirror cleared up within seconds and the driver mirror also cleared up but took a bit longer. It's nice to know that my mirrors are heated, thanks guys for the input really appreciate it.
