Started the Yukon this morning heading to work, and no sound...no FM stations, no XM, no CD...no sound what so ever....do the speakers run on their own fuse or does this sound like something more than just that?? haven't had time to look at the fuse block, so just wanna get some input on what to try and look at to fix this...

thanks in advance

 

The head unit itself is working though right?

 

check the fuses and the back of the radio, the harness may be loose but i'm pretty sure the bose speakers run on the same amp as any other factory speaker.

 

display is working fine, just no sound.

 

if the radio turns on its not the fuse... maybe they amp took a $hit.. the amp is on the bottom of the center console

 

Some of these can be corrected with a reflash using Tech 2. Check with your dealer. There used to be a TSB, probably still is.

Amp failures are not uncommon....

 

I thought the bose systems had a seperate fuse for the head unit and the amp?? I am pretty sure the last trailblazer I worked on with bose had a "radio amp" fuse.
