Hi!
I saw this thread with the audio schematics and thought it was exactly what I was looking for. Thank you for that! I was wondering if anybody has any knowledge about the problems in the audio system?
I have a 2015 GMC Yukon XL and the warning sounds (when the car starts, when I turn the turn signals) started to disappear. They could be faint when I start the car (I believe they are wired to come out of the left front speaker under the windshield) and then disappear completely. Sometimes they come back. The radio works however, including from that left front speaker.
Could the wires responsible for this just be loose or would you think it's a bigger problem? And I was wondering if you could point me to where I would find the Radio X1, X2 and X3 connectors inside the car, please?
Thank you!
