Heated mirrors not working

    My truck, 2002 2500HD ext cab short bed, has heated mirrors that do not work. I do not think they have worked since I purchased it in April '08. Everything else on the truck works fine including the rear defrost. I checked a few fuses that I believe run the system and they all are ok. That's where my knowledge on the subject ends. :confused: I thought I would ask if anyone has any insight before I send her to the dealer for diagnosis. Any help is great.

    please advise to your results, same truck an they work for sh*t. I think you have to have the rear defroster as well as the vent selctor on something.....I wish GM had just put a damn switch in. Instead you have to rub your head while patting your belly, and jumping up an down.

    They just wear out easily. I can get the mirrors and heating pad (behind the mirr) 2 wires hooked up in the back and usually get corroded..The mirrors just pop off. Let me know if anyone needs replacements. I would need to know what year, side, and if you have directionals in it..

    The manual says just push the rear defrost and they go on. I'm going to do more research on it and I'll be sure to post results.

    Yes the mirror heat is controlled by the rear window defroster.

    And yes the heater grids die with age. Yours are likely both dead.

    Easy enough to change though. :waving:

    I have found posts on other discussion forums saying that you can "pop" off the old glass and "pop" on new glass. Is this accurate?

    Yep, you "pop" not only the glass but the plastic plate it's attached to out of the mirror housing as an assembly. Not tough at all.

    mikelawtown, what can I expect for a cost on this? My mechanic thinks it's the heating pad also and is getting a price to fix it. Just checking to see if he's in the balkpark.

    Well I fixed it. I went through the trouble shooting I found on the web. Specifically, I pulled the plastic trim off the door on the inside of the mirror and chcked the wiring harness to see if power was getting to the mirror. It was the orange wire that brings power for the heated element. Obviously make sure the heated mirrors are turned on then check with a volt meter. I had power there so I figured it was the element in the mirror like many suggested. My mechanic said the bulletin put out states that the passenger side has a tendency to go first. I then follow instructions by Mikelawtown (thanks!) that said to point the mirrors in and grab the end and pull off. Sure enough the glass broke like someone said they would so be sure you are ready to replace before pulling them off. The new one had two simple wire connections to make then pop the new glass on the housing behind it. Pretty simple. Oh yeah, the dealer had the glass for $60 for each side. I felt like a snob while I was researching them but the next storm will be my first ever with the heat. Can't wait!

    If I have the power extending mirrors are they heated as well? Its an 05 2500h. I never really knew if I had the heated mirrors, because I never saw a button. Is it the same on all GMs I also have an 07 Escalade.

    It would say "heated mirror" on the mirrior with like 3 wavy lines next to it.

    Simply way to tell...if the truck is equipped with the rear window defroster then your mirrors are also heated. If not then they are not heated.
