Does anyone have an exploded view or instructions on how to disassemble the rear view mirror?

My mirror wobbles and I'd like to take it apart to fix it, but my dealer says it's a sealed unit and the whole thing has to be replaced for $600.

I have the mirror with the OnStar and the compass display, and the auto dim.

Alternatively, can I replace the mirror with a non OnStar and/or no compass mirror? I don't use OnStar and likely never will and the compass, while nice to have, is not necessary.

Thanks.
Stan.

Hey Zeeman, I just fixed min last night because the prior owner mounted a laser detector on it.

Mine wobbled at the connection to the window, not the connection that the mirror swivels on. Mine was a super easy fix.

So to remove it, just grab the base that is connected to the window and swing it 1/8 turn tword the passenger side. The full mirror will disconnect from the window, but the wiring will still be attached.

I grabbed some black foam tape about a 1/2" thick and 3/8" wide and placed a 3" piece along the area in the back where there started to be ribbing. The foam will help to take up the slack.

Reinstall the mirror in the same way you took it off. It helps to have a second person there to line you up so nothing gets broke. I was trying to reconnect mine with a slight angle down and I was not able to get it the first three tries.

Once it is connected, the wobble should be gone. Total cost is under a dollar and less than 10 minutes.

That is how you remove the mirror from the base. The reason the mirror shakes is that the pins that keep it solidly in place on the windshield mount get bent from adjusting the mirror a lot.
I removed my mirror, removed the (3) pins, straightened them out and re-installed. The shake was gone. I try not to adjust the mirror too much, just so the pins will stay straight.
Here is a PDF of how to remove, fix and re-install.

Thanks for the reply guys. I will give this a try.

Hi Stan


I had the same problem a few years back and instead of tearing it apart and fixing the pins I put a grade school style eraser and wedged it between the top of the windshield and the mirror. No wobbles till this day . You cant see the eraser from the outside of the car because of the tint running across the top of the windshield

Someone on the form posted the eraser fix and so I though I would give it a try

Nice fast and easy fix

One day I will tear into it and straighten the pins though

I'd be afraid to touch mine at this point. It would probably fall off into my lap.

Thanks for the assist guys. That PDF really helped.

Is it easy to replace? I don't need to fix the old one, they're giving me a complete new assembly. The mirror backing on mine is deteriorating around the compass and there are lines that go across the entire mirror (from edge to edge) that are in the backing material, ie, inside the unit.

So in order to take off the old one:

1. unhook the electrical

2. grasp the base of the mirror, turn it clockwise so the top rotates to the 2 oclock position. It comes free.

3. Rotate the new mirror towards the 2 oclock position, push it onto the windshield mount and turn it counterclockwise to the 12 oclock position. It snaps in place.

4. Re-hookup the electrical, you are good to go.

Seems that should only be like a 7 - 8 min job tops.

Not a sealed unit. The pins get bent. I took my pins and turned them 180°. Some people have fabricated new pins out of drill bits.

It took about 10 minutes. The pins in the mirror are not that stiff. The mirror was ok for a bit but it's back to doing the wobble thing again. Going to try that drill bit idea. Should last longer using a steel bit.

The drill bits work better then any of the other fixes I have tried...The problem with the original pins is they're to flexible and bend to easily allowing the mirror to wobble...The drill bits are stiffer and won't bent out of shape , allowing you to adjust the mirror without bending the pins......WW

The crazy stuff we do to our cars. I've seen and done some interesting things as well. I guess thats the fun of the toys.

Seems like a poor design. Like I said mine doesn't wobble, just getting it replaced due to a defective mirror. Once mine is adjusted I rarely move it. Can the pins be bent during installation? so the dealership might inadvertently bend them while mounting the new mirror? Mine is nice and tight now, no wobbling issues....but there are blemishes inside the mirror on the backing. Streaks going across the entire length and the edges deteriorating around the compass window. There since new....but postphoned the replacement just for this issue, didn't want to trade in one defect for another (the wobbling).

I did the eraser fix also...
