The bottom line on heated mirrors
I've had my '02 Chevy 2500 for about five years now. It's a great truck, but the heated mirrors haven't worked since I bought it. I've been all over this mirror issue for about a month now:
First off, you have wires in the back of the glass similar to your rear-window defroster. Check to see that you are getting power to the mirrors by pulling off the acces panel on the inside of the door on the front of the window. There are two tabs that hold this triangle shaped panel in and a third tab to pull up on. Pull from the top, and you'll see how it works. Once you have the panel off, you can see a bundle of wires that go to the mirror. Disconnect the white connecter fitting. Turn on the rear defroster and you should have power to the orange wire. Turn off the R. defroster and you should have no power. If you have power to the orange wire with the R. defroster on, then the problem is in the mirror.
From reading on the web, it seems a lot of people have bad mirror glass. It seems that the wires are very fragile and prone to breakage. The dealers out here in Colorado want $65 - $75 for the
chevy mirror glass. I did see a part number some where and looked it up on gm-parts.com, but the illustration wasn't correct for my truck. The dealer did give me a part number, but it was for the whole mirror assembly. If you want to replace the mirror glass, it just pops out of the mirror, but you will probably break it prying it out.
I bought a cheap aftermarket mirrior on Ebay, and boy, is it cheap. The glass is not the same, so you don't get the same view through the mirror (hard to describe). The mirror I bought shook terribly (lots of vibration) and the controls moved the mirror in the wrong direction. I thought I could live with all of that, but it snowed last night here, and upon turning on the defrost the mirror cracked in half top to bottom. The seller is going to send me another mirror.
My recomendation would be to confirm the mirror has power to it, and then to replace it with OEM
chevy mirror glass. I would get a good part number and get it off of
www.gmpartsclub.com and buy it there.
May the force be with you, and hopefully this helped everyone here.

I recently bought a 2002 Silverado LT.
Althought the power adjustment works on the outside mirrors, the heating function does not work on either mirror.
the manual says turning on the rear window defroster turns on the heated mirrors.
Neither mirrors' heating function work would leads me to suspect a power supply fault.
The owners manual only shows one fuse in the engine compartment fuse box.
That fuse appears fine but I changed it anyway. Neither mirror still works.
Is there another fuse in either the panel to the left of the dash or under the center console???
Any other suggestions?
Thanks
