My low beam haedlights don't work, but all other lights work. Any Ideas?

it is possibly the bulbs both burned out at the same time...seen it on the Prius~not sure how that you figured out the bulbs were still good, but could check to see how you're wired there...could be a RELAY, might be Grounding to the headlight can, or chassis~ for a 2009, enough moisture or god forbid salt, the ground connection can become "iffy" so that's be a good place to check~ All connections from the battery and the lead connection from the - cable to the Block...as that one warms up and cools down every use, moisture can work it's way in...this is a troublesome concern...and certainly one could disassemble this connection, clean it with a wirebrush and put it back together~ that could only HELP the situation~

I guess I should have been a little more detailed, I took the bulbs and fuses out and visually inspected them. The filaments in both bulbs are okay. I checked both fuses and neither are blown.

okay...that only leaves the switch then...see you've deduced your own problem...our work is done here~ :)

one of these...take your pick~ https://www.google.com/search? q=2009+Mitsubishi+Galant+ES+headlight+switch&biw=1360&bih=6 49&tbm=isch&tbo=u&source=univ&sa=X&ved=0ahUKEwjC5YD- guTKAhUDGR4KHSn7AbwQsAQIGw

I was also reading on another thread that it might be the front ECU. That you should be able to feel a click in the ECU when you switch it from off to taillights to headlights. I can't feel anything but I can hear a clicking when I go from off to taillights, but not to headlights. Yesterday I asked if that could be an indicator, but as of right now I haven't received a response.

check your fuses~

computers can be reset~/rebooted~
