Is there a way to wire the auto dim mirror so on/off button dims it?

    I assume it's because I have tint and a baby seat in the way but the auto dim rarely works (it does work, just not most of the time).

    I was wondering if there is a way to re-wire the auto dim mirror so on/off button dims it (on = dim, off = no dim)?

    long shot, i know

    TIA!

    I don't have the OEM auto dimming ....

    Are you saying your rear window is tinted? Then, YES....that'll have an affect on how the mirror dims. Since you have window tint - that's doing the same thing anyway. The tint will defeat the purpose of the mirror.

    THere should be a 'sensor' on the mirror. Make sure this sensor isn't dirty or blocked. This sensor is what 'reads' the light levels and makes the mirror dim.

    Not exactly sure what on/off button you're referring to...... Are you referring to the on/off switch on the mirror or your on/off switches for your lights?

    It would be nice to dim on demand. Damn thing doesn't dim when I need it to like when a super high bro truck is behind me and blinding me.

    I would have to say that this could be possible but would probably require completely redoing portions of the circuit board in the mirror. You would have to really know what you are doing in electronics. It could be feasible but tricky.

    I'm not at my truck now so I can't check but I believe these mirrors work with two sensors, one in front, one in back, and it only dims when the back sensor reads more light than the front. (They have to have two sensors otherwise it would dim during the day) So if you block the front sensor with black tape the mirror should always stay dim, until you press the auto button, which should turn it off. I haven’t tried this, but in theory it should work.

    So...you would spend 25 hours researching and rewiring your mirror just because ONE or maybe TWO bro trucks are behind you and blind you? Seems like a waste of time & effort.

    Instead of messing with your mirror..... do what I do....

    Have some fun by adjusting your side mirrors to direct his lights back in his face. ;)

    I woundn't do the actual rewiring but it would be a nice available function . This is socal and there are tons of bro trucks here.

    I had the same problem. I do a lot of night driving and the auto dim sucks on these mirrors. Do what I did. I took some tinted film about as dark as x-ray film and taped it over the front sensor on the mirror. It lets in less light making the sensor think that it's darker than it actually is so when the sensor that is on the other side facing the back of the truck picks up any light it dims the mirror more than normal. It works great now. If you want to make it dim all the time just put a small piece of electrical tape over the front sensor.

    Thanks a ton for the suggestion!

    I too drive a lot when it's dark (although it's early morning).

    It would be nice if the on/off button on the front of the mirror was for dimming on demand.

    The windows are tinted but my state doesn't allow but 35% tint, so it's not nearly dark enough to prevent brightness of traffic.

    I'll give it shot, thanks again bro!

    Yep, small piece of tape on the front works. I noticed mine would pick up too much light from my GPS at night and never worked.
