I'm trying to figure out if it is normal to have a yellow tinge to my mirror glass, or if it is indicative of a bad piece of glass.

The heating and dimming don't work any more, so I thought perhaps the color might have changed due to a chemical reaction of the dimming liquid inside the mirror.

I've seen the blue glass a few times, as well as typical "glass" glass with no color to it. Are these different in some way?

I'm curious to know when the heating circuit comes on. I would assume it would engage below a preset ambient temperature, but am probably wrong.

It stands to reason that the dimming is always active, no?


Once last thing:

I've tested the dimming connectors with a multimeter and the voltage seems to fluctuate depending on the light hitting the sensor on the rear-view. Does that indicate proper function, or is further testing reuired?

I've tested the heating leads as well. They seem to be reading ~12V all the time, yet they are not heating... That also seems a bit redundant - heating the mirror on a hot sunny day, that is.

Any and all help is appreciated!

The fluid insode is dark brown. The very thin layer of it between the glass layers imparts a yellowish cast. When it leaks out the mirror becomes clear. Unfortunately, I'm now working on my third RH mirror thanks to winter and I suspect, an ice scraper.

I see a yellow/brown tinge on some pre- and post facelifters. Often on one side. Darker = more kaput
