Mind sharing what fuses you changed? I should try that too but I haven't had any luck from the quick searches I did in the footwell area.RESOLVED:
I changed the fuse even though it was not faulty - maybe it was just getting weak and all the lights went off. Like it never happened.
Went to Autozone and got a free replacement battery - this time installed with zero issues.
What will happen going forward? Who knows. But so far she is running just as before - and as I mentioned above, we crossed 300,000 miles over the weekend!
Was it the passenger / driver side footwell or the fuses in the engine bay?
Super glad you got it figured out and keep us updated if the issues comes back for any reason.
