I have a similar issue. My driver’s side door and dash speaker will work on occasion (getting more and more rare that they do work). Mine is a 2019 that JUST crossed the 36k mark. I know the speaker isn’t blown because it sounds fine when it does work. This happens no matter the source (phone, radio, Sirius, etc).
Because of this, nav thru CarPlay will not work at all, meaning I pretty much have to keep my eyes OFF the road to figure out where I’m going. I bought this truck CPO not even 3 months ago (free Sirius is still active).
Because I drive a lot for work, I’ve already eliminated the CPO warranty, so it looks like I’m pretty much screwed unless anyone has any ideas.
Usually it seems to work after I do a soft reset, but only for one good drive before it’s out again for longer than it worked. And yes I’ve used the balance fade screen to test and when I move the indicator toward the front drivers side I just get no sound at all no matter the volume.
