Hi,

Just about the time I was going to discontinue my Onstar subscription anyway, the unit began malfunctioning. It repeatedly gives me an annoying message saying that it can't connect to Onstar. This happens not just when the key gets turned on, but also going down the road in the middle of a radio program. I can even hear it giving that message after I'm out of the truck and the door is locked.

Onstar tells me that they have tried to deactivate the unit, but in that process they were unable to contact the truck, and that it's a Chevy hardware problem. I can't find a fuse dedicated to this sub-system, nor do my internet searches provide any clear path to a solution.

Is there a way for an owner to stop the Onstar component from functioning, or is this something I'm going to have to go to my dealer for?

Thanks for any help you can provide.
