Installed an auto dimming temp/compass mirror in the car
Last year I bought an auto dimming temp/compass mirror out of a late model pickup or Tahoe at a swap meet. I finally got around to installing it while I did my headliner installation. Last night I snapped a couple over exposed pics for those that care. If our snow ever melts and I can get the car outside in some natural light, I'll take better pics. Initially I was going to post a tech article, but now I'm not sure. The hardest part about this project is getting a switched 12 volt power source, and frankly, that wasn't hard. This is a nice mod for anybody who wants to modernize their interior a bit without actually changing the appearance. This is one of those nice subtle mods that almost nobody notices, yet it adds just the right "something" to the feel of the interior that helps you forget that you're in a 20+ year old car. I love knowing what the temp is, and the auto dimming mirror is cool too.

I love what you did with the mirrior and i want to get one in mine now, but how the HELL would i do the wiring? and is there any modifications i should do to do this?? Im really eager to do what you did.

Re: Installed an auto dimming temp/compass mirror in the car
I'm going to have to look for one of these mirrors for my car now. Like you I enjoy doing subtle mods that make the car more enjoyable. I just did heated mirrors on my car, and other than the little heated mirror symbol on my left mirror lens, no one would ever know about them.

Does the mirror have the temp sensor and compass inside? Or did you have to install the sensors outside?

Re: Installed an auto dimming temp/compass mirror in the car
C4 Corvettes come with heated mirrors that turn on with the rear defroster. The wiring should be pretty simple, though you would be wise to incorporate a relay so that you don't overtax the original circuit. I had thought of doing this in my car, but since it's garaged and not driven in bad weather, there wasn't much of a point in my case.

Re: Installed an auto dimming temp/compass mirror in the car
I had this idea in my head for the longest. My dad's '02 Savana has the same Rear view mirror.
Im a little confused about one thing though, are the sensors built into the unit?
Damn, I dont know if i should do this. My car has map lights built into the mirror. =/

Re: Installed an auto dimming temp/compass mirror in the car
That looks great Jim.I installed an auto-dim mirror in my '83.It's the simpler mirror GM used(I think it's a Donnelly but could be Gentex - have to look).And the heated exterior mirros are a neat idea as are the wind deflectors the C4 Vettes use.
Turboman you can buy the mirrors pretty much self contained except for the outside temp sensor.

Re: Installed an auto dimming temp/compass mirror in the car
I know i'm waking this thread up from the dead, but i recently got a pontiac grand prix as a DD, and one thing i REALLY love is the mirror! I'm fixing to re-do the interior on my 87 IROC, including the seats, headliner( t-tops) and carpet. So for the mirror, I assume all the GM ones were pretty much the same? I can pick up anything with temp/compass? Where/how did you run the wiring for the temp sensor? Underneath the trim on the front of the windshield? I have t-tops, and I'm trying to figure out how I would do that. Or maybe, i can just hide the sensor under the upper console trim? Where did you get the sensor, and how much wire did it take to run it to the fenderwell?
Thanks!
Thanks!

Re: Installed an auto dimming temp/compass mirror in the car
I just ran the wiring behind the windshield pillar trim, then down behind the dash, out through the passenger kick panel to the temp sensor in the passenger wheel well.
But... next time I blow the car apart, I'm moving that temp sensor up in front of the radiator. Where it is now, it's very slow to respond to temperature changes. Apparently there's very little airflow in the area behind the passenger wheel well.
As for the mirror, the mirror out of just about any GM vehicle should work. In fact, as far as I know, any compass/temp mirror out of almost anything will work... just verify by looking at the shape of the mount. I think that the company that makes these for GM only makes them in the gm-style mount, so even if it comes out of another car (like a Subaru for instance), I think it's going to be the same mount. But... I'm speculating, so you should check before buying.

Re: Installed an auto dimming temp/compass mirror in the car
Many of the GM dimming mirrors were made by Gentex, but the one pictured is made by another company and I don't recall the name off hand. It usually says somewhere on the mirror. The Gentex were on Fords, Chryslers and GM vehicles BTW.
The mounts are different for different years and they're typically larger than the standard style. You might be able to swap mounts if they're similar enough but I haven't done anything like that with the newer mirrors. I started a thread to gather as much information on the mirrors themselves but I don't have anything on the temp sensor etc. Located here. >Link
Nice job on the install!

Re: Installed an auto dimming temp/compass mirror in the car
I'm assuming that mirror you put on the car doesn't have any lights on it? The thing that would keep me from doing something cool like this is, the only interior lighting I have in my convertible is the two lights on the rear view mirror.

Re: Installed an auto dimming temp/compass mirror in the car
I can't comment on the mounts from other styles, but my mirror mounted directly to my original windshield mount.
As for lights... nope, no lights. Stick some brighter 194s in your wheel wells and you'll be all set.

Re: Installed an auto dimming temp/compass mirror in the car
Damn it I was gonna do this and thought I would be the first. Oh well I know now that it really is as easy as I thought it would be. A couple of questions though does your mirror have the airbag off light? I know some have the airbag light and onstar controls which I would like to not have since our 3rd gens don't have either. does anyone know which mirror would not have these or which model of vehicle to work for.
As for lights in the mirror I'm sure there is one that has them, these mirrors are in about every gm vehicle (maybe not cars though I guess I have never seen one now that I think about it)

Re: Installed an auto dimming temp/compass mirror in the car
They do sell ones with map lights, there's a seller on eBay that will even let you choose from like 6 colors for the display. Apparently it even has a wire to make the map lights come on when the doors are open like the stock setup, and it's got buttons to control a garage opener. Only thing it's missing is the light that shines down onto the gear changer, but you could just wire a little LED to come on when the headlights are turned on. I'm planning on getting the mirror I'm referring to eventually, but I need to take a break from spending money for now.

Re: Installed an auto dimming temp/compass mirror in the car
Have you seen this mirror with lights? I have been looking and I don't think they make em that way. That is the only reason I hadn't done this mirror conversion on my car (I did it on a z71 truck I had). But your idea of lights in the floor area is great. I have a 92 z28 and it did not come with those lights (the holes are there in the panels, but no harness or lights). I think I'll add the lights down there and then switch mirrors....thanks for the idea!
