Look on the mirror face itself. If it has a little white etched waves (look like heat waves) then you have them. From what I understand the tow mirrors all have the heat.

 

Yeah I havent look that detailed at my mirrors. I know what you are talking about the little waves... If thats the case with the heated mirrors than I may have them, cause the build sheet specifically calls out the tow mirrors

 

Yea I didn't realize it either. When I first saw the defrost I looked for the little wires on the back of my truck but i didn't have them so I looked all around and deduced that they had to be the mirrors. They worked well in PA. Had some ice and snow on the mirrors. So started the truck, hit defrost and scraped the wind shield, when i was done i looked and the ice had melted and fallen off

 

Eric does yours have them? And did it call them out on your window sticker? Not sure if I have them... over lunch Ill look

 

My 2005 had the folding/heated mirrors. My 2008 does not. Both have the tow package.

ok does everyone with the heated mirrors have the squiggly marks on there mirrors? I am gonna test my mirrors out tonight to see if they are heated. I dont have the waves, but I cant imagine having all the options except Nav and then the foldable mirrors having no heat... I have the heated rear window, so Ill let ya all know my findings
