No light on mirror for OnStar

[frosty1_4me]

Hey guys, I hope someone can help.  I've taken my truck to the dealership and they say it's Onstar that is the issue.  I've called Onstar (because it doesn't work in the truck) and they say it's a hardware issue.  I'm getting the run around.

 

There is no light on the mirror for the onstar.  Pushing the buttons does nothing.   If I disconnect the truck battery and reconnect it, the light comes back on but only lasts a little while and it goes unfunctional again.   OnStar tried to say that the onstar module needed to be upgraded as it was to old, (3g to 4g) when I called the dealership they said it was upgraded.

 

One guy at the dealership suggested it maybe a body module that needs replacing, which I could do if I knew that was the issue and which one since there are many.  If I do replace a module does it need to be programmed with OnStar again to work?

 

Any ideas?

thx

What year is your vehicle?  Could be that it isn't/wasn't upgraded.

To upgrade is NOT FREE provided you can still upgrade an older vehicle.  I seem to recall Onstar changed around the 2013 model year.

What year truck?  When the light comes on, is it GREEN or RED?

Its' a 2014.  When the light does come on its green.

when it is green can it communicate with onstar, if not you have an antenna problem

Not sure about that, i'll give that a try and report back.
