Does anyone know what the indicator light on the lower far right of the mirror is for? Sometimes it is red and sometimes green. I can't find any info in the users manual.

That is the OnStar connectivity light, it should be green most of the time. If you are not
subscribed to OnStar it really doesn't matter what color it is, if it stays red all the
time there is probably some fault in the OnStar circuitry/antenna.

Thank you Wicz. My OnStar appears to be working normally, but the light is red most of the time. I notice when I last called OnStar, the red light started blinking.
