In my 2002 SC430: The interior rear view mirror has an indicator which does not light up when I press the auto button. It does not auto dim at night either. My headlights auto on/off so that daylight sensor works. Ive checked the mirror fuse but not sure if there's anything else causing this. Do these mirrors go bad, or has mine been broken ? What items do I check and or test to diagnose and repair the mirror?

Mine went bad a couple years back; the little green light in the mirror would go from on to off when the button was pushed but the exterior mirrors and interior wouldn't dim. I ended up trouble shooting by taking the mirror off and opening the case up, I figured it was already shot so nothing gained if I broke it worse.

Fairly easy to open and whatnot. I compared the mirror to the one in my 06 LS and with the plastic cases open noticed the internal components were completely identical so I swapped them.

Still not sure what happened but I was able to order one used on eBay for a fraction of the cost that the dealer wanted.

Hope that helps

Thanks for the info. My mirror LED does not light up and nothing happens when I press the button. Fuse is good. How do I get into the mirror to check if it's receiving power?
Thanks! Marty
