Replacement Ballast?
 

The drivers side low-beam on my '05 G35x has been randomly going out while driving. I simply turn off the lights, and turn them back on, and it kicks back on. This to me seems like more of a ballast issue than a bulb replacement (figures...) Took it into the stealership and they want $385 for an OEM ballast and $125 for labor.

Is this something I can do myself and save some coin? Will it involve soldering, or is it simply taking the old one out and bolting a new one in? Last question- anybody have any recommendations on where I can get a new (possibly OEM?) ballast for a good price?

Your help is very much appreciated!

I had cheapo defective bulbs that caused this on my car, I had 3 bad ones (guy I got them from sent me a replacement pair). I know because the dealer replaced my whole headlight, only to find out it did the same thing. OEM bulbs in and issue went away. They are cheapo ones I got off a guy on here who was clearing out LEDs. If you are running aftermarket bulbs, something to check out anyways.

No soldering is required, you just need a phillips head screwdriver. Basically you have to jack your car up, and pull out the plastic lining in the wheel well to allow better access. The ballast is screwed (with 3 phillips head screws) to the bottom of the headlight. There's a plug or two you have to disconnect, and you're done. You should be able to find a ballast on eBay for pretty cheap. I got one, brand new, for about $80 shipped.

Thanks for the info guys- exact reason I love this forum. I picked up a bulb from autozone (although I'm doubtful it's the bulb) and just ordered my ballast on ebay- $93 shipped, a heck of a lot better than $385! Looks like I'll have a project to work on next week.

Anybody ever have a similar problem?

I had a ballast go out completely about 6 months ago. Thought it was the bulb at first, and I was lucky enough to find a member here with a couple for sale. Now I have a replacement if the other one goes out.

Yeah, my ballast went out...I thought it was the bulb at first. So I went to NAPA and picked up a bulb, came to find out it still didn't work, so ordered a ballast and bingo. I brought the bulb back to NAPA being that $hit was $80 and they gave me a hard time about returning it, but I argued back and forth with them and they finally gave in. Don't take the bulb you bought out of its box. Take the bulb that's in your other headlight and test it in the bad one and see if that's it. This way, if it's the ballast, you can bring that bulb back and save quite a few bucks!:biggthumpup:

That's funny you mention that- I asked the guy at Autozone what they're return policy was, in case I didn't need it, and he told me the same thing- once it's opened, they won't take it back. For $100, that's going to be my second shot. I was thinking I'd do exactly what you suggested- swap the bulbs when I install the new ballast.

Finally had a nice day, so I swapped ballasts. Fingers crossed this works! If it does, I just saved myself like $400 by not going to the stealership!

Thanks again!

Goodluck dude.

I had the exact same thing about 3 months ago. One you get all the tyre off and unscrew all of the plastic shielding from the wheel well it was pretty easy. The hardest part was just getting the clips with the wiring to pull loose.

RVANDERWERF- Did you have trouble with your ballast? My driver side head light was glitching the other night but it stopped quickly....... possible cause and solution here. THX

^+1 on the trouble getting the headlight unplugged. Sore fingers!!!!!

Haha yeah man- I didn't swap the igniter, just the ballast, but you're right- that little clip on the ballast was a pain- literally! After having done it once, I am confident in doing it again in 1/2 the time, as with most things with the G.:biggthumpup:

this was happening with a fauly set of bulbs i bought

Thanks man I'm gonna try this 2morrow. I been trynna figure this out. For few days now.

Hey man, same thing is happening to my G. I turn on the headlights and notice the driver side flicker, and a minute later it turns off. Turning the switch off, then on, turns on the light...then it turns off again. I saw a good deal on lightbulbs but I think I should replace the ballast first. Do you know if Matsushita is a good brand?

Ballast supplier
 

Just curious if your ballast still works and if so, where you got it? I have the same issue. Thanks for any help you can provide.

Just make sure u have a torq key with security hole in the middle, thats what the screws are to replace the balast

Thanks!

There are many places (like online junkyards) that sell these types of parts on eBay for cheap. I got my replacement ballast for $63 dollars on eBay. They usually have a steady supply too. Always check ebay and amazon.

Thanks for your help! Just received mine from Ebay, keeping my fingers crossed that it works.....

Does anyone have a part number to reference? 2 choices: just he ballast; ballast and igniter (with cable) should the igniter be replaced as well? Had mine go out on me last week, already had one cop give me hassle for only having 1 headlight.

Swap your ballasts from left to right, then igniters left to right if necessary. If the problem follows the part, replace the bad part. If it stays on that side, check the bulb or wiring.

I bought mine here....http://www.ebay.com/itm/NEW-OEM-NISS...id%3D100102%26

I'm not sure whether I needed the whole thing, but at $70 vs $546 from the dealer, I really didn't care. Note, you have to remove the front bumper, so may want to do both while you have it apart. I have turned my headlight switch off of Auto because I garage my car and my mechanic said that might be wearing out the hardware (always cycling the lights on at crank up). Good luck....

Your mechanic is right, the ballast has a limited life in such I would never recommend using auto lights.

Any links to vids on gaining access to headlights?
 

I'm not sure how to get access to the the headlamps and removing the ballast. Any links to vids?

watch a video on replacing front bumper and thats how to get access, 10 mm socket is all u need and maybe an extension, 3 bolts though, make sure u have security torque bits too ( the torques with the hole in the middle) the bolts the hold the balast are torque with security holes

here a good vid, just a heads up, i dought u need to remove the ones from ur splash shield under ur car

I've taken off the splash shields /Inner fender off and had access to the low beam like that

that way works too, i guess if u dont mind the tight squeeze, the splash shield will just be annoying bc those bolts are more than likely all rusted

Guys don't make this harder than it is. Just jack up the front of the car and the ballasts are accessible under the lights by removing the undercover IIRC. You do not have to take off the bumper or mess with it at all.

G35 coupe
 

Hey guys, just some info for everyone. There was a Recall on the 2006 g35 coupe COMPLETE headlight assembly, as well something with the air bag .

I'm in the process of fighting infiniti regarding the engine oil burning issues with the 3.5 . There was a Recall on a bunch of the engines for oil consumption issues. My car goes thru a quart of oil per 500km of driving.

The airbag was an easy fix, basically they just tie wrap the harness together and add a couple more on either side to keep the wires from moving.

The headlight recall if probably going to be tricky since they don't even manufacture the headlight assembly anymore I think...

Good luck with the oil burning, it wasn't a recall it was a TSB that only applied to cars under warranty.

EDIT: Also, the headlight recall really only affected 2006 models since the recall happened during 2006 and all those 2007 model year cars had their headlights replaced before the cars were even sold. Technically it was 2006-2007 though.
