: LH Mirror Glass

10-28-12, 03:25 PM
I've been giving some thought to trying to modify my export version mirror glass. I had never posted this before, but when I bought export mirrors so I could upgrade to power folding, I discovered that the LH mirror glass had a "convex" tip. It's actually bent outwards which eliminates the need to add a small stick on mirror. Now, I haven't added a stick on mirror either, because... well, I just won't do that so I think this would be a very cool mod. Since side blind zone isn't available on export vehicles, there is no choice but to mod what's available.

For those of you that are curious, it is heated and electrochromic.

To complete this, I need to have a very close look at mine. I would need to transplant both the heating element and side blind zone alert indicator. This will be tricky, but I have completed other mirror projects on similar assemblies where I've had to separate the glass from the mount. If I do this, I'll post more later. My point to posting this thread is to let everyone know there is a "convex" option available. The glass should be available as a service item as I see several options listed in the catalog for replacement glass & mount alone. This is a direct replacement for any 2005-11 STS as long as you don't have SBZA.

The power folding mirrors that I purchased were for the STS-V (Export), model code 'DX'.

I do still have my broken mirror glass with SBZA from my deer hit if you need some pics or dissection assistance or something.
I wonder if since they obviously look the same as the turn signal mirrors if the LEDs are present or if they could be swapped directly from another car with signal and SBZA (eBay is full of DTS mirrors that have SBZA and signals) then you could have chevron signals in mirror plus SBZA and the body side signal.
While looking for replacement mirrors I am rather certain I saw domestic versions of that mirror available as well but I don't recall it being auto-dimming.

Thanks for the offer. I'll have a look a little later and let you know about some pics. When I upgraded to my power folding mirrors I did test the assembly to see if there were LED's present for the turn signal. I wasn't able to come to a completely definitive answer for a few reasons, one of these was because I didn't want remove the assembly from the back of the mirror.

I have mixed feelings about the turn signal mirrors, given there is a signal lamp on the side of the fender. GM always specified only red LED's in the mirrors. This might look quite out of place given I have amber on the fender and in the tail lights. More than likely I could change the red LED's for amber, but there is the question of whether it would look too redundant with the fender signal. The other part is that these are powered by the driver door module. I suspect the STS module won't support this. Now, it would be possible to wire these directly to the turn signal circuit (as I did with my Bonneville).

The mirror glass may be available on domestic cars, but I personally haven't seen one yet (although we don't have many STS's here). These are made by Magna and they won a 2009 PACE award for what they call the "BlindZoneMirror".

I have a issue well at least i think it is. When im on the high way an want to give it my car clocks out at 120 and wont go higher the engine would rev but its like theres a golf. Please help thanks its acaddilac sts2003

You've ended up in a completely different topic in the wrong forum. This forum is only for the 2005+ STS. My best guess is that your car is programmed to limit you to this speed, based on the original tires installed. Some exported cars were also limited to 120 km/h. You may want to check with member of the correct forum.

Here are a couple of photos of the mirror. You can see on the face, there is a dotted line extending from top to bottom. This is permanently marked on the mirror and shows where the tip is curved outwards.

I've completed the first step, perhaps the most risky... I've separated the mirror from the base. I'll need to do this to the mirror on my car, including salvaging the heating element. If I can pull this off, the rest will be easy.

Well I cleaned out the trunk today and pulled out the broken mirror that I had tucked into the spare tire well for later usage.

Here is what I found out.

Shot of the back:

The cover just pops off (held in place by some 2 sided sticky foam tape):
Rather than relying on direct view of the LEDs, GM decided to use little reflectors to make better usage of the light.


Here you can see there are 4 Amber LEDs used on the board to light up the SBZA:
(There are solder pads for 7 LEDs for turn signals as well)


Another shot of the board out of the mirror:
The 6 pads in the lower left corner are what is used to power the turn signals. (2 appear to be for extra support of the connector)

Sticky adhesive on the back:

There is a little window cut into the heating element to allow the SBZA to work, the heating element is completely non-transparent.
So if one wanted to have heated mirrors with signals as well with SBZA you would have to find a heating element from a different mirror that would fit (not likely).

So if you do decide to use the export mirror keeping SBZA will be a chore if you want to keep heated mirrors.

Since when did the sts have turn indicators in the mirror?!

Well it never did. But it certainly could have. It uses the same module as the DTS w/ SBZA but its missing the 7 LEDs and the window in the heating element to light up the glass.

Turn indicators in the mirrors sounds like something from Western Auto. I rented a DTS with this feature and it was really annoying, especially at night.

When I retrofitted 09 DTS mirrors on to my 02 deville (since my driver mirror lost its electrochomatic fluid - seal breakage) I got a set with turn signals and SBZA indicators, I wired in the signals (no way to make the SBZA work).

At the time I was working 3rd shift (11pm-9am) and I thought they were a nice touch.
Too bad I only drove the car with them for a month or two then I got the STS.

Never did. But if I recall the 2005 sts sae 100 had SBZA and turn signals in the mirror glass.

SAE100.... The STS that GM should have built. That car is such a tease.

Yep. http://mirrorministries.org/wordpress/wp-content/uploads/rearview-mirror.jpg.

Thanks for posting those pictures. Can you tell me how bright the LED's are? A couple of weeks ago I disassembled the mirror glass from the export mirror I purchased. After I removed the mount and element, I held quite a bright flashlight to the back but very little light came through. It made me wonder if there isn't a mask/sealed region between the layers of glass where the SBZA symbol sits to permit more light to pass?

I modified the mirrors in my Bonneville to include turn signals. At first they were quite apparent at night but now I can't say as though I even notice them anymore.

Well I didn't power up the module outside of the car to know how bright the SBZA LEDs are but I did turn on my phone's LED (iPhone 4) camera light and lit up behind the mirror to see if there was anything obvious about how the mirror was made.
The light only came through where the 2 cars are, it was certainly dimmer than what the phone does on its own since it was going through the glass.
I believe that there is a slight etching to the glass that allows more light through and there is the little black insert to give the light its shape.

I'm glad I don't have signals in the mirrors. I agree with Koz on this one.

Had em on a 2004 Dts. Driving in an area with no lighting, then signaling, messes with your night vision pretty badly. Forces your eyes to readjust to the darkness again. Looks cool to me though.

Basically, you have confirmed that it doesn't seem I can transfer my SBZA indicator to my export mirror. I believe the reflective coating is on the front surface of the rear glass, between the two layers that comprise the mirror. The black insert is a mask to ensure sharp edges on the image. Since I can't get between the glass layers, there is no way to remove some of the reflective coating to allow light to pass. Intensity of the symbol as it sits now would simply be unacceptably low. Oh well, guess I won't be adding my export mirror.

Again, this is preference. If you had them I can pretty much guarantee you wouldn't even notice them after a few weeks.

Good now you can sell those mirrors to me... lol
