My left turn signal stopped working. Neither front nor rear lights, and there's no indication on the dash that the lever has been moved. It's not the bulbs nor the fuse, and the left-side lights don't work when the four-way flasher is engaged. Right bulbs -- with turn signal or four-way -- are normal. Any hints are most welcome.

 

i think it may be the turn signal switch

 

sounds like you need a new relay for the left side i believe its in the driver side kick panel. you should be able to swap the right with the left one. i have seen a few of these accords with that problem come into my honda dealer.
