Does anyone have a DIY on a good way to approach the fog light bulbs?

 

grease up your wrist and slide it behind the splash shield. the passenger side is a little tougher since you have to squeeze by the washer fluid reservoir. i think if you search there are detailed instructions on this site but it's a relatively easy job. look in your owners manual or the excellent FSM sticked at the top of the G37 Sedan forum.

edit: this is for the fogs in the bumper not those integrated into the main housing (there are a few DIY stickies for that as well).

 

Use a pen-light to get oriented. Turn the bulb housing and pull it out of the fog assembly, rather than trying to disconnect the wire harness while still seated.

You will get scratched up. Helps to have thin little girly arms.

 

go through wheel well, very easy and you're able to actually see the fog housing

 

I just took the wheel off and it was a piece of cake then to try and work with the little gap you get .
