I accidentally flipped the terminas when jump starting my vehicle. The main fuse blew up and I replaced it. But the steering wheel buttons do not light up, they're working but not lighting up even when i switch on the headlights manually (not uing auto), this also applies to the (traction/hazards/trunk) button. Every single button in the car works and lights up, but these buttons work with no back light.
I tested the fuse box, some fuses were blown and got replaced, and i did test the fuses after replacement to check if something blew up again due to a short circuit, but its all okay.
