I have the not-onstar rearview mirror and my map lights will only work when it is positioned a certain way, which is usually just all mangled and twisted around. Is this bad wiring or a bad mirror or what? It's been this way ever since I bought it back in February.

 

It's the wiring. Mine does the same thing on all 3 mirrors that I've had lol

 

I have 1w leds in mine and only the driver side works right. The passenger is barley lit (a candle is brighter). If I put regular bulbs back in it works fine. I've tried multiple good leds and none work correctly on the passenger side for some reason.

 

Yeah mine doesn't work all the time with purple LED's and sometimes when I'm just driving down the road, The map lights start to kind of flicker lol

 

- I have the same problem in my 03 SS with NON-OnStar. LEDs that sometimes flicker, dome light, too. I wiggle the cable in the back, & everything is fine, ... even the rear-view headlight dimmer thingy stops working & the green light goes out.

I dunno, but I am going to figure it out in the spring, or hard wire a switch for the maps, & see to it that the rear dimmer gets power as needed without fussing.

 

The harness is probably destroyed. I was playing with mine earlier & noticed the wires are pretty thin. Using a window shade is probably the cause of it. Dealing with the same thing, when the harness was pushed up everything worked, but let go & its got no power..

 

Has anyone found a fix for this? My 04 non-onstar does the same thing. ONLY works when wiggling wires. auto-dimmer does the same too.....

 

You usually have to get a new pig-tail and splice it in.

 

Cool. Thanks for the quick responce !!

 

The one mirror I bought would never work because of the plug. They all must be bad or at least the majority have this problem. I use the old mirror out of my lumina and have never had a problem. These mirrors are also in the 5th gen monte.
