The fuse worked on many prior generation trucks. Not this one. They have gotten quite advanced and several things are tied into that module apparently. I am friends with a GM tech who pulled the whole circuit up and he tells me it cant be done without issues. Yet, there is a video on you tube and it can be done. My tech friend told me several people have asked about this and he said he feels its safer to just cut the antenna. But cant remember that had one draw back also.? The blackbox is also not an independant module and cant be disabled without screwing up several things. That box is not there for no other reason than to be used against you. It is intentional. Why do you think Onstar is mandatory and included in the sticker price now??? To help you...or to monitor you? Literally dont have a choice, think that says it all. No one wants Onstar more than GM and its for the information for their purpose.
