Question edited for clarity.
Question moved to model category.

It depends what the part is Bettie? Some specialist parts can only be purchased from a local dealership or Nissan direct. Many parts can be sourced on eBay with new or reclaimed used items. Consumable parts like filters, spark plugs and brakes pads can be purchased via Amazon. There are also specialist parts suppliers like Rock Auto. Check out the link, the maker is the first link.

You can also just Google 'year make model (the part)', and you get listing like this one for brake pads

Question edited for clarity. Your vehicle is not an 'infinite. it is an 'Infiniti, and it is an 'FX35', not and 'FX3', plus it is 'YouTube', not Tube'. If you can spell it you can find it :>D

YouTube is for videos, not for finding fuse box data. The Radio is listed as 'Audio' and has 2 fuses. BUT, did you disconnect the battery recently? It the 'radio' asking for the code?

is the only thing not working the cigarette lighter? the fuse that operates it is usually the accessories fuse, it normally operates the interior light as well, which fuse box have you checked,there is most likely one under the bonnet & there also may be one under the dash as well, it might well be that the cigarette lighter element is the problem,try another lighter....hope this helps....cheers
