Why would all the dash lights go out when the park and or headlights come on - 2002 impala 3.4L The problem has been intermittent. Fuses are good.?
Same problem... Its the Headlightswitch.
I didnt believe it at first considering I never use it due to
DRL switching modes for me, but yeah that's the problem or was for
my 2002 Chevy Impala
