Headlight problems

have not seen this one before........


driving home at dusk yesterday and was behind another vehicle and noticed my left headlamp looked dim. shut the lamps off and ran parks and fogs the rest of the way home.

got home pulled into the garage shut down fogs and reactivated headlamps. sure enough the left one had everything dimly light ( low, high, parks) removed headlamp cleaned a little corrosion on the prongs and re assembled. worked fine again. took apart again this morning to add some dielectric grease to prevent further corrosion and now the issue is back! WTF!!

need to drive it tonight to go to school and back so this has to be fixed quickly. any ideas????

Sorry to hear that, Sawgunner! If your headlamp is still out after you attempted to resolve the problem, I would recommend seeing your Chevy dealership for service. If you need help finding a dealer near you or have further questions, please direct message me anytime!

Are the little rubber gasket thingies still in the plugs? They should be weather proof, something is not kosher here.

I'm sure the dealer would blame the aftermarket housings even though they have nothing to do with the bulbs or the wiring.

I know on the Buicks they has issues with the connections going bad and causing the lights not turning on. Happened on my fathers LaCrosse and the dealer said its an issue on this and other GM models.

all the rubber seals are still in the plugs, got it mostly working again so far. ordered new black headlights and looking around for a new headlamp harness or pig tail.

The new lights should come with the harnesses in them, the question is, is the problem there, or further into the wiring? I'd check voltage at both pigtails and compare, then ohm check the grounds, if they are the same, hopefully the new lights with the new harnesses will fix the issue. If they are different, the problem is somewhere in the car wiring.

got the new light assemblies in and so far no issues. but they have only been in for a day will have to wait and see if i need to go find another car side headlamp harness.

found out something new though, getting a car side headlamp harness is not as easy as go to the yard find one and grab it. one obvious difference is police package vs normal and with fogs or without (seems simple enough) well it also depends on if you have remote start or not! don't ask me how that ties into the car side headlamp harness but apparently it does
