My Hypertech programmer says to remove the Onstar fuse before programming the truck. Ther dealer told me that there is not a fuse for the Onstar, he is full of it, if it uses power, it has a fuse.Does anyone klnow which fuse the Onstar is linked to.

this is in your manaul, page 5-128.. and before you say you don't have a manual there are online manuals at the top of the page in the FAQ. If I can find it, you can find it ;-)

and yes..the dealer is full of Sh*t

I don't have the manual to my truck, I just bought it used. If there are online manuals at the top of the page in FAQ, I am way too f stupid to find them. If there are owners manuals somewhere in this huge forum, I'd like to know where so I can program my truck. The dealer is a turd.

click on the sticky at the top of this section that says LLY FAQ..
then click on the link that says ****Online Manuals****
pick any year model and go to the page I quoted.

See, I was too stupid. I have the manual, thanks, I don't see onstar or the rearview mirror listed for any fuses. I would think someone has run into this before on here. I'm going to search some threads to see if it has come up before.

not trying to be a harda$$ here, just trying to get everyone to use the information that's already here and save on repeated posts.

per the manual-
underhood fuse box, page 5-128
fuse marked INFO, right next to radio, page5-131
Info controls Onstar

Oh, that's in the 06"manual. I looked in the 04' manual because as I understood it the 04'-05' were the same & the 06'+ were different. Thanks.
