2006 G6 Headlight problem

NT1078 · 03-21-2011, 05:50 PM

Hi All,
Today I've developed a new problem: My passenger side headlight low beam bulb will not come on. Normally one would think replace the hedlight, but I also noticed the passenger side parking light does not work too. I checked the fuses under the hood, and noticed the #9 mini-fuse (passenger side low beam) was blown. I replaced it and it blew right away.

Wire short somewhere? Anyone else ever experience this little PITA?
Is it possible if the headlight blew on the passenger side it's creating a voltage draw and blowing the fuse everytime I try to replace the fuse?

Thanks,
Adam

take out the headlight housing check the wiring going to it...take out the low light bulb and see if its blown. probably going to be the only way to tell is to take it outta there

Thanks for your quick, helpful reply. I will replace the bulb for good measure just in case it's gone sour.

I will report my findings.

Okay,
I've changed both bulbs (parking light and low beam) and the problem persists. When I unplugged the head light harness, I counted 4 terminals, and the 5th one, the one sort of in the middle looked burned and corroded. Is there supposed to be 5 terminals where the headlight connects to the wiring harness?

Yes. Low beam, high beam, side marker, turn signal and ground.

Got it! Thanks for your help, guys.
There should be five terminals in the main connection as stated above. One of my terminals rotted away for some reason. I cut the wire on each side of the connector and installed a butt type connector instead. Replaced the fuse and voila.

Thanks again!

Please go here and report it. I thought I had mine fixed with electrical parts cleaner to get rid of the corrosion and electrical grease to keep out the moisture. It didn't help as I believe the corrosion had already eaten away too much of the metal in the connectors. My right headlight connector is burned up and the left is so corroded it will not last long.

This is a safety issue that GM should fix, IMO.

Makes me wonder what other electrical problems will come our way if GM was so cheap to use crappy connectors for something as important as our headlights!

Funny, same thing happened to me today!!! Replaced the $17.00 bulb for nothing.... Will check those connections tomorrow!!! I noticed the orange parking lamp worked when turning on the blinker, but not with the headlights on...hmmm We'll see tomorrow! Glad this site is open!

Yes, the turn signal will continue to blink at least but the parking light portion will not work. The high beam also worked on mine, but not the low beam when this was happening. Check the harness connection where the headlight connects into the main harness, it's a white connector IIRC. One of the terminals may be burned. Cutting on either side of the connection and installing the butt connector worked great for me. No problems since.

Does anyone know where we can buy new connectors or is it just a dealer thing?

Any auto parts store, just need to get the connector that fits the bulb.

Hello every one got a 05 g6 base model got a problem with my headlight every now and then when i go over a bump my passenger side drl ligh cut in and out signal wrks fine high beam wrks fine but the low beam keeps cuttin in and out in the fuse box the low beam relay is braced with a piece of styrfoam friggin guy who sold it to me never told me about it if i take the styrfoam out both headlighs low beam won't wrk. Please help me.

So I said "Screw it" and decided to just clip all of the wires and just get rid of the connector itself...Had it hard wired for the past few months with no problems! If my passenger side decides to act up, I'm doing the same for that side
