The warning lights " ! " is on on my Infiniti FX35.

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?

The most common reasons an INFINITI FX35 speedometer isn't working are the vehicle speed sensor (VSS), a faulty speedometer, or an electrical issue.

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

All three lights came on at the same time while I was driving last month. The dealer said it was the sensors. Had them replaced for about $750

Easiest way is to unhook the battery on your vehicle and leave it unhooked for a couple minutes. All the codes will be erased and the light will go off. If the issue is still going on that initially caused the light to come on, it will come back on though.

Good Luck
