    OK I finally got my truck in for the mirrors, and the steering shaft... Well they just called and said my mirrors are working fine.. than I have to turn on the rear window defroster for them to works...(NO KIDDING... :angry: I know this ) my comment was that they do not melt snow/ice/even a lite covering of water(like fogged windows)... Tech said they get "warm"...

    Is it possible that they do not get "warm" outside in the cold...but work fine in the nice warm shop?? I know for a fact last winter they would melt snow/ice or what ever off the glass.

    Also do you know who hot the mirror glass is suppose to get. I have access to an IR thermometer to check it.

    I don't have a schematic but someone must have one here. If we assume they are supplied 14V (when running with a charge) the resistance is set but the coils of wire within or behind the mirrors. So the temp must be OK? Make sense? If you were putting out less voltage you would have other problems like dim headlights for instance and mirrors that wouldn't melt.

    I believe they will time out after awhile with the rear defogger. May be that is happening and you don't realize it????

    I've had trouble with my heated mirrors too (2001 2500HD) I put 5 on so far. 4 were covered undr warranty. The fourth was out of my pocket. I had problems getting the warranty. Seems to give off enough heat in the shop but not during cold conditions. So I went to the dealer and showed the them the temp difference from left to right using a infrared contact thermometer. I don't rember what the difference in temp was from side to side. But enough to warranty it. GM repalcement parts are 1 year from purchase. So if one goes out before the warranty is up I show the parts manager the difference in temp then remove the "glass" and pick up my new one.

    I'm sure you are aware that the whole mirror assembly does not need to be replaced. Just the "glass" can be removed. The important factor is to show it to the parts manager before you remove the "glass" because removing the "glass" will crack it and they may be very skeptical. Also compare new "glass" resisatnce value to old "glass" resistance value. My experience is the preformance degrades it doesn't just stop working.
