#170 of 173 2004 TRBZR Left Low Headlamp out
Sep 07, 2012 (7:41 pm)
I tried everything to find the source of my frustration in regards to the left low beam headlamp;
1) checked the fuse
2) the HDM relay (i even swapped with blower)
3) Replaced socket to lamp, tests good.
4) removed the grille and swapped headlamps, this only confirmed the left low lamp (wiring)is the culprit.
5) To be determined. I tried to crack the fuse/relay but unable to.
Any other suggestions?
Early issue was the only intermittent operation with the headlamp...then after my Father In Law and I worked on it...it operated just fine and then a few weeks ago it no longer works. I am deploying soon and I don't want to leave my wife with less than acceptable car.

I just dealt with a 2006 Chevy trailblazer issue. The turn signal did not light on the front passenger side. A new bulb did not solve it. I replaced the flasher relay module, still did not solve it. the headlights started going dim and working sporatically. It turns out that there are four chrome raised bolts in the engine fuse box. They appear as they only hold the inside cover in place, as it snaps over them. I tightened these down and everything is working as they should. After quite a bit of money spent, I was glad to find this solution and had to share with the group. I would try this before heading to replacing the head lamp relay.

I was driving down the road and the headlights just turned off, all running lights were on but headlights were of. They would not come back on even if I switched the headlights from automatic to manual. I would have to pull over turn off car and turn back on with the headlights coming on occasionally only to find them turn off again driving down the road. Any info would be great, don't want to keep having the headlights turn on and off while driving.

Easy fix for this very common problem, replace your headlight relay in the fuse box under the hood (Drivers side next to the battery). If memory serves me, it's relay #43. 2 ways to get you out of trouble while on the road...#1. switch #43 with the fan relay #46 right next to each other (same exact relay). #2 take the relay out and put it back in 10-15 times, which will clean the contacts...sometimes this will work too.
