2004 mazda 6 low beams don't work but high beams do

SOURCE: LOW BEAM LIGHTS

Hi Rich Million,

Check the bulbs for the low beam problem and if they're ok, check the fuses under the bonnet (hood) which are found in the fuse box. If you've already checked those, go to the fuse box inside the vehicle.

Still no luck....remember that there are fuses and relays inside the cabin behind the kick panel.....You may find that there is a problem with the main fuse box.....If you drive over rough terrain, check the connections under the main fuse box....even if your roads are all smooth, it's still worth checking.....

you have to change just the low beam bulb. Ive already changed mine twice in my 06.

no

my suggestion is that you check/ replacr the HDM(headlight driver module) relay in the main fuse box located under the hood near the battery.

Possibly the bulbs. Take a look at them; they have 2 coils per bulb, one for the low beam and one for the high beam. So it is possible that the more used low beam burns out before the lesser used high beam.
