Red light on mirror

[Asells]

Just noticed today that the red light on my rear view mirror was on. I see according to onstar that they have detected a problem. What kind of problem, just with onstar? Dont know how long its been on as I usually dont pay attention to that.

I don't think there is a problem. I'm not 100% sure but I think it means your on star subscription is no longer active.

Call onstar and see what problem they detected? If I had to guess I'd say low blinker fluid.

If its just an onstar issue I dont really care as I dont even use it.

My subscription is set to expire today. I'll have to watch and see if the green light changes to red...

Red light indicates an issue with the OnStar system. Probably the communications module or the backup battery in it has gone bad. If you are under warranty I'd check it out as there has been issues in the past with bad OnStar communication modules killing batteries.

Where is the battery and module located.

There is definitely a problem with the OnStar system. The accounts on my other 2 vehicles have been expired for years but the light on the mirror still shows up green so that's not what it is.

From the manual:

 

• Solid Green - the OnStar* system is ready.
• Flashing Green - when you are on a call.
• Red - indicates a problem. Push the button or call
888.4.ONSTAR (1.888.466.7827) to speak to an OnStar Advisor.

I also noticed that my compass isn't showing up either. Could this be an issue also with the onstar? I did disconnect the battery the other day for about 30 minutes.

Seriously. Call onstar and ask them. It'll take 2 mins and no guessing from these forums.

I tried the blue button today and didnt connect I will call them tomorrow and see whats up.

I have a 2016 sliverado LTZ Z71, I do use onstar and have a subscription, my light went red about 6 months ago and won't connect to onstar and my compass doesn't work either so I finally took it to the dealer and they indicated the module is bad, $775 to replace it and then mabye the antenna will need replaced also.

I have owned my chevy's over the years and this is really the first issue I have had but it's still gonna be an expensive fix.

My red light came on yesterday compass not working still able to contact on star talked to advisor I do not use it but was told by them and my dealer the module is bad.

oddly enough the compass button on my radio is still working and changes direction while driving my truck is a 2014 Silverado
