Bulletins

[BigO]

How do you find out what updates GM has for our trucks. I tried the Vechicle Calibration Web site and it seems to never work.

I complained about something on my truck and dealer fixed it because there was a bulletin on it. How can we find out what bulletins are out there for an 01 HD with d/max?

Thanks
