Question about 2004 Infiniti I35
I can't be as easy as just replacing the bulb like Shaan86 said. The owners manual says to only have it changed by the dealer. The aftermarket bulb suppliers will not take responsibility for any damage if you try to do it yourself. They all recommend that you use a trained technician. There must be some sort of electrical issue that needs to be addressed for xenon bulbs that is not needed for halogen bulbs.
You're right, its not that easy. I just did mine on a 2003 - I35 when the dealership told me it would cost approx. $220 for the bulb and 1 hour shop labour to repair(about $350 Cdn when all is said and done). The required bulb is a D2R-35W. Your local parts dealers in Canada will have it for $125-$150. I was told NOT to disconnect the battery as this may impact some default electronic settings which will then require a reset. Here are the steps:
- the headlight assembly must be removed as you need to get access to the back of it which is impeded by the battery on the driver side and the washer fluid/ coolant resevoirs on the passenger side. There are 3 bolts which hold the assembly in place. The first 2 are visible and easy to remove. There is also a snap on clip at the bottom of the assembly which disengages with a little pulling. The 3rd bolt is tucked up under the fender and is a real doozie. Ideally, you can hoist the vehicle and remove the inside wheel well covers to access the bolt. In my case, I was able to access the bolt by peeling back the wheel cover enough to fit my hand in and blindly finding the bolt while on my back. It was corroded and sheered off when I was finally able to access it(10mm closed wrench) but dont worry as the 2 remaining bolts are strong enough to hold the assembly in place when re-installed. I'm sure the dealership would have done the same thing and not bothered replacing the corroded bolt as the passenger side xenon light had been replaced prior to me owning the car ( I found this out when I couldn't understand why the assembly would not come off on the driver side so I decided to remove the passenger side and lo and behold the 3rd bolt had been cut). Removing the passenger side also gave me insight where the remaining bolt on the driver's side was located.
- detaching the remaining lights and well as a plug from the assembly is very easy and now you have access the back. Remove the phillips screws on the metal housing cover and you're almost there. Turn the base socket that reads High Voltage(I was told not to worry about any voltage being present) and pull it away. The base of the bulb will now be exposed. It is held down by pressure clips. Remove the bulb and install new bulb exactly the same way that you removed the old one. Handle the new bulb by the base only and very carefully. Touching the glass part is not advisable. And that's it. Reinstall the lamp assembly minus that nasty 3rd bolt and you're good to go. Access to the back of the assembly is key. If you think you can do it without removing the lamp assembly, go right ahead. Another cautionary note is the colour of the light. You may notice that the replacement bulb colour may not be exactly the same(bluer or whiter). My replacement bulb is slightly whiter but barely noticeable. If you're fussy you may want to replace both blubs. This project should be done by someone who has relatively good handyman skills.
