Question about 2004 Chevrolet TrailBlazer
Lowbeam head lights not working I have check all fuses. replaced both bulbs. don't know what else to work with
Most of the time on the Trailblazer it is the dimmer switch that goes not the Module. Try replacing the dimmer switch and i think it will take care of ya troubles.

SOURCE: i got a 2004 chevy
If it is anything like my 04 GMC Sierra, there is a relay panel under the hood. In that underhood box where you found the fuses, there are also relays. They pop out (the diagram is on the lid of the box). After the GMC hit 200k, the relays started going out. The high beams are on a relay, the lowbeams are on a different one. You can pop one out and replace it with the horn or foglight relay if you want to check it out. I am betting that the DRL bulb just happened to go at the same time. Mine go out regularly..I would say around every 10-15k miles. I don't know if this helps, it is just something that I have run across with a similar vehicle.

Hi Miles, Have you replaced the head lamp bulbs and maybe used a higher output? That can overheat the fuses and or the connectors. The over heating and damage will usually be caused by loose connections causing high resistance and heating. Make sure the connections are tight. Regards John
