I took my truck to the dealer for the A/C TSB. I was informed there was a recall for a OBD software update on the truck. They did not go through with the A/C TSB saying that the software update would effect A/C operation and I had to see if it now worked properly.

Have you guys heard of this? Somehow I don't think the software update is going to fix my A/C not blowing cold in hot weather but I am seeking your opinions.

Thanks!!
