What did you do to your NNBS GMT900 Tahoe/Yukon Today?

So for some reason my Bose system is messed up, I only have sound coming from the a-pillar tweeters and the r/f front door panel and the sub in the console. No sound whatsoever on d/s front, 2nd row doors, or d-pillars in the back. Any thoughts from you audio guys? It is a stock non nav head unit. I think it has been like this for a while I am just getting into trying to diagnose. If it is not something simple I will rip out all the factory and go full aftermarket.

I did remove the rear audio control panel in the rear of the console. Don't know if that has something to do with it or not.

@mikez71 @j91z28d1 any thoughts?

I can probably look up the wiring diagram later if @mikez71 doesn't already have it handy. I've not been into mine, so I don't know what does what off the top of my head.


I wouldn't be surprised if the bose amp. gave up, on other cars when you have bose everything runs thru their stuff.

Sorry I don't know about the rear panel and the audio,
Could be speakers/amp/headunit...

If the passenger front works, but not the driver... I would focus on driver front first
..since the rears could have something to do with the rear control panel..

ordered new wiper blades these do not last for years but they do not lift even at 130mph (confirmed) and they are cheap a comparable set of bosch is like $50+ at the store
I have thought about switching to the ppv wiper arms but they stick out a lot
