2003 Trailblazer Headlights
2003 Trailblazer has an intermitent problem where both running lights (low beam headlights) will go out while driving. I immediately checked both fuses (both tested good) and changed both just to be certain. One time the running lights started working after changing the fuses (a coincidence?). Now lights are out again and the fuses are good. How do I troubleshoot this problem?

I checked light connections; everything is tight and no corrosion is present. Problem of both low beam headlights going out simultaneously continues. Lights will go back on after Headlamp Driver Module relay (46) has been removed and re-installed.

a couple of nights ago I had an issue with our 04 TB the headlights would not come on. (of course Murphy was involved as it was dark & RAINING)...anyway ...i pulled all 4 fuses they looked fine so i put them back in then tried the lights again & they came on & have worked fine since ( crossed fingers) i called the local dealer they had never heard of this problem and like i asked them how do you recreate something like this for them to check it !!!!

Have an '03 TB, 80K miles. The Low Beams just quite working (high beams are fine). Can't find anything wrong. I'll try the relays and let you know what happens. Thanks for the head's up.
