A buddy of mine is a senoir tech at our local GM dealer. He checked and had one code "loss of data" He reprogrammed and so far so good. He said if the problem comes back the Drivers blend door and the rear module might need to be replaced.

BTW he said pulling the HVAC fuse doesn't do anything for it. If that's true or not, i don't know.

If the problems come back I will update this thread.
