2002 Chevy Trailblazer

I just had a front headlight go out so I replaced it. When I first put it in both lights worked fine, now my low beams don't work at all. I checked the fuses and everything is ok, any suggestions??

Very frustrating!!

RE: 2002 Chevy Trailblazer

Fuses 3 & 6 (10A) in the underhood fuse block should be the left and righ headlamp fuses, respectively. The other things that the headlights have in common are their voltage feed through the HDM Relay in the underhood fuse block. This relay supplies power to the low beams for DRL and normal headlight functions.
