    '98 Deville Northstar, Rear View Mirror - "Dimmer" not working

    Hello Folks,

    Trying to fix my rear view mirror, it has the "auto off" feature, when switched to "auto", the mirror is to dim under certain light conditions.

    I recall this feature worked s few years back.

    When I press the "Auto" button, the green light does "not" illuminate?

    All comments are appreciated . . .

    Thanks.

    Check the fuses. Diagrams in your manual.

    Thanks for your suggestion.

    That would be the Park / REV fuse and that's good - so that's not the problem.

    O.K., we ruled that out

    Is the wiring into the mirror good? Is the connection to the mirror snug, clean, and unbroken?

    You are brilliant . . .

    Somehow the 6 pin connector came lose from the mirror - now how dumb do I feel . . . (a bunch).

    It's always something . . .

    Thanks for taking the time and your suggestions - as previously noted, - this is a GREAT forum.

    This is why we are here

    Don't worry about it. I'll stick my car keys in a different pocket, and when I go to get them, I panic for 5 seconds cause I think I lost them



    Anytime you have a question, stop on by!

    Interesting, one of my outside mirrors doesn't tip in reverse and the other doesn't dim (the one has never dimmed, the other one not tipping is a new occurrence). Going to have to pull my mirrors out and check the connections.

    The right one is NOT supposed to dim, AFAIK. Just the driver's side. For the not tip in reverse though, that sounds like a good idea.

    Before you start pulling the door apart, have you checked your driver personalization settings?

    Sounds like they are operating as designed. Only the drivers side is supposed to dim (it's tied into the rear view electrochromatic auto dimming system) and only the passengers side tilts down when in reverse (parking assist feature).

    I was thinking ^^^that^^^ as well, but then I read:

    So I assume he's talking about the passenger side mirror not tilting.

    I could have sworn the drivers side one tipped down when I first bought the car...

    Oh well, I guess it will bother my OCD slightly less if that's how they are supposed to work.

    Ranger - indeed, a simple fix, unlike the complete rebuild of my northstar.

    Again "thanks again" to all the folks on this forum.
