I posted this on the other A/c thread, but her ya go....
I finally have a chance to post.
My dealer took my 2014 GMC Sierra in without an appointment, gave me a Cadilac STS loaner (blah), and fixed the a/c, recharge, and new bracket. I came prepared with a print out of the known issue and the bracket that needed to be installed. So they gave me no bull shit. While it was there they did my inspection for no charge.
The repair bulletin PIT5331//OP.CODE 4415010
Part numbers Description

The jury is still out on whether it blows as cold as before. I say no, my wife says yes.
