    Default Power Towing Mirror Disassembly

    Hi I have a 2006/7 Sierra 2500 HD Classic. The mirrors are manually extendable, with power mirrors, heated and LED turn signal.
    Recently the drivers side mirror has been misbehaving. It wouldn't move when the mirror wasn't extended but would when it was. After extending it and putting it back the power mirror would sometimes work for a bit then die again.

    Now there is no way that I can get the power mirror to move electrically I have had the mirror off and checked that there is voltage getting to it when the switches are moved, so either I have broken wires in the mirror housing or a dead motor. At the moment I am leaning towards broken wires due to its earlier behaviour.

    Now for the problem, How do I get the mirror housing apart to check the wires?

    Any help gratefully appreciated

    A hammer!!!!!!!

    Someone broke my driver's side mirror last winter. I looked at replacing the broken parts before I decided repair and replace were about the same price.

    The only way to get to the screws that holds everything together is to remove the glass. My glass was already broken, but it looks like the glass will "pop" out if pried in the right place. But, it also looks like it will break real easy.

    You have a 50/50 chance of removing the glass without breaking it, I removed one on a Bravada and it had 3 plastic adjustment rods attached to the back of the glass. They are threaded into plastic nuts, 4.5mm socket, 1/4" ratchet, 12" long extension and patience and you'll have a good shot at it.

    Thanks for the replies. A hammer would certainly do the trick, but I may regret that approach. I'll look for the plastic rods and nuts tomorrow. A number of "suggestions" on the webb says to just force the mirror and it will "pop off" from its retainers, but I am a little wary of this.

    The mirror glass on full size trucks is held on by a circle of clips that attaches to a circular plate on the motor pivot assembly. To take the mirror glass off, look behind it and you will see the circular part where the clips are. The trick is to pry it in the right place that you can get a couple of clips to release and then you can move it around to release the rest. If you can get a long flat screwdriver in there, it can be helpful for getting those first couple of clips released.

    Trickey territory, no matter what we can tell you it takes feel and knowing when to stop adding pressure so it wont break. Go very slow and prob use penetrating oil with a straw to help the clips pop. What i try to do is instead of prying use a flat head and twist it so the head is appling pressure at the clip and not on the glass (if you get what im trying to say use the head like a cam). Other than that godspeed my friend and i wish you well.

    Again, thanks for the responses. I think I have applied as much pressure as I feel safe in doing. Would anyone have a pointer to a parts drawing of the mirror. As it is on the drivers side and it only gets moved when I tow the trailer, I think I'll leave it as is for the moment, a manual mirror is better than no mirror!
