Thank you JohnWR, and thank you others for your ideas.The reflash TSB is the only thing that is one and done.
As I mentioned further up, can anyone confirm that the TSB number is 060849016?
I have been looking for the detailed TSB that a GM tech would follow, but I find nothing to print out and hand to the service center. I am trying to save some labor charges paying them to research what I can do here. At $130/hr, I'd like to be charged a fraction of an hour of which they are known to do.
In the mean time, I will try the fog light trick. In my other vehicles, the fog lights don't function independently. The regular head lights must first be on for the fog lights to function. I guess the Sky is different.
