08 charger dash lights cutting out

Find someone with a good scanner , check for codes in the car , an autel scanner will do an all system scan , then go from there ,snap on scanner also probably head light switch

you can actually scan more then emission codes now?
that's cool, ill look into that

I may be way off base here, but my 02 trep dash lights freak out when the dimmer knob is near the max intensity detent.

I tried messing with the settings on the dimmer, but once they go out, they are out

i might pull it apart when i get it back home and see if i cant clean the switch itself
