I have a similar issue: Low beams won't work (both sides happened on the same day -- definitely not the bulbs), but high beams do work (so do running lights). I think I'm going to dig into it more tomorrow, but if anyone has seen this before / dealt with it, I'd appreciate the advice (and I'd rather not spend the $147 at the dealership to get it diagnosed by h-nda).Low beams quit working for the second time on my '04 EX. Not the bulbs (replaced twice). Dealer replaced wiring harness 2 years ago. Any ideas?
