Mirror/onstar Lights Flicker...

[Kevin8520]

Hi all! I have an 03 Silverado 2500HD Diesel and I have a small problem. The truck is equiped with Onstar but it does not work. Not only does OnStar not work but the lights on the mirror (for the onstar buttons) flicker on and off. The autodimming mirror works, the compas and temp display work, but the onstar button does nothing when pressed. No other lights such as dash or radio lights have this problem.

 

Does anyone know what the problem could be? Would a new mirror do the trick or is this something else electrical I need to get checked out?

no one? I have heard of other people having this problem but no one seems to have a solution.
