Turning off auto dimming mirror by default?

First I need to thank everyone here for all the good info as I got back into a Wrangler after a 10 year hiatus... from Pat and the pricing info, to Hilldweller and his headlight advice, I also go a lot of amusement from a rant thread turned bacon, beer & boob dialog a few months back...
Anyway, one annoyance I'd like a solution for is the auto dimming rear view mirror. In my old GC I turned it off shortly after I bought it and did not turn it on again until I sold it. On the Wrangler I turn it off, but it defaults to on when I cycle power. I did not see anything in the programming thread and was wondering if anyone knew how to keep it off?
I have seen a few people talk about flipping the mirror so map lights were up, but I would rather find a way to prevent the mirror from turning everything green and keep the map lights.

The auto-dimming mirror is one of the things I'm most looking forward to - not sure why you'd want it off?? But hey, to each his own. I'd open it up and pull a wire, being careful not to break anything so that it can be put back on for resale. I doubt something like a mirror would be part of the programming.

I am not a fan of the auto dimming...drives me nuts that it's on every time I get in. When I turn it off, it should be off till I turn it back on.

I am not sure about the Wrangler, but many times there is a wire signaling "reverse" (roughly the same as turning 'on' the backup lights), that disables the mirror's dim. Possibly if there is something like that, you could simply tie it permanently to +12v?

Interesting idea. Had hoped the was a software (programming) solution. So many of the systems are computer controlled...

Agreed....

I don't really like auto-dimming mirrors and I wish it would stay off when I turn it off.

Because backing out of a dark garage into bright daylight is harder when the mirror looks gray.

It's also harder to see at night as well. At least for me. It's... "muddy".

I think one solution is to tape over the light sensor so it thinks it's totally dark, all the time.

Pretty sure the auto dim disables when you put it in reverse. Most of them do.

Manual says it does say it turns off in reverse, but I usually turn around when backing up...
I'll try CrispyB's trick with some electrical tape until I get time to play with the wiring. I can't stand how the mirror blacks out if someone with headlights on, is behind you for more than a minute...

Well, that confirms it. My auto dimming mirror does not work. I see absolutely no difference between night and day. I press the button, cover the sensor and still nothing. It has a dim green light showing all the time is that normal?

I thought it only dimmed at night, when there were overly bright headlights detected right behind you?

HighwayTrout: You have to hold BOTH map light buttons AT THE SAME TIME and for SIX SECONDS (!).

I get in at night, and the factory tint on the hard top is dark enough, but then with headlights behind me, I can hardly see anything.

So, to disable (just for this trip), the User I/F guru's decided you need to reach up while driving with one hand holding in both buttons for 6 seconds while your hand blocks the mirror. Oh, and hope you pressed them BOTH at ONCE or afterwards you will be left with 1 or more Map light on. Brilliant.

Has anyone ever solved this? dcgibbons, I'm especially looking at you!

Summarizing the issue in this old thread, I, too, would like to set the mirror auto-dimmer feature to "off" by default.

That doesn't mean I don't want the feature to work, so no snarky responses needed. I just want it off by default.

Hmm..my mirror never dims unless the roof is off, the factory tint is dark enough that the mirror stays as is all the time.
