4.0

Hi all, new here. Wondering if someone could help. I bought my 04 TJ last year and a week ago something strange happened. All my lights except my headlamps stopped working. The icons for them don’t even light up on the dash. I’ve replaced the fuses, stalks, and multifunction switch. Is it a bad...
