Which light, the one on the right side?

I found that when it comes on for me, I'm in area with NO reception. Has happened a couple of times.

See if you can scan for codes on the truck (AutoZone does it for free IIRC)...its probably throwing a UXXXX code...check the "info" fuse in the underhood fusebox also...

yea it's the light on the right side of the mirror, I haven't been anywhere diferent, just since i took it to the body shop it quit working. And it's always saying, "phone unavailable" which is very annoying. I'll have to take the chip out to take it to stealer, im afraid they'd screw it up. I will try the "info" fuse.

Try pulling and then replacing the INFO fuse. Or just disconnect the batteries and then reconnect them. That will reset the OnStar.

You can push the button and call into Onstar and they can reset it.. Mine did this a few times not to long ago. Said it was no big deal, might have been a signal issue?

It could be the cell phone antenna disconnected. You can get to it by dropping the glove box.

None o the buttons work not even the emergency button. All of them say phone is unavailable. I have to use my cell phone to contact them. I will try calling them though and see if they can reset it anyway.


And I will see if I can find the antenna.

no luck on resetting it, found the antenna unplugged it and plugged it back in, no good. If I ever figure this out I'll report back for others that may expeience the same. Thanks for all the help and suggestions.
