Currently my glovebox and ashtray lights are out and my ac display will not work and my climate control buttons are useless. I tried replacing the fuses by my foot and that did not work. Then I opened the hood and found 2 fuse boxes, I checked the fuses on both and tried replacing a few and still no luck. I ****ed up messing with the wire connected to the ash tray light, anyone have some advice on helping me find the fuse?

 

Find your service manuals here (thanks to NICO club):
http://www.infinitiservicemanual.com
"pg.pdf" is Power and Ground.
Check:
Fusible link # C 80A (doubtful)
Fuse # 71 in your IPDM (likely)

 

#71 was the lights problem thank you but my A/C is still not running. The control display lit up and the temperature screen did not when I initially changed the fuse but the second time and on neither are working. Im searching through those files for a fuse...

 

So the A/C controller will light up with the lights but wont do anything along with the blank display and the seat heaters are not working or lighting up. I have read as much as I can into the manuals and researched every forum on the internet and no one seems to have ever had the same problem as me... I looked at the blower fuses, A/C fuse, Radio Fuse and other etc. fuses and still no luck. I have a 2004 g35 coupe with a Metra Dash and pioneer radio, the radio has not gone out during this whole ordeal. Living in Texas I wish it was a problem with the radio instead...

 

Yes, even with the manuals it takes considerable digging. Looking at your car's Power & Ground and the ATC (Automatic Air Conditioning) manuals, I see there are at least 3 fuses which could cause the AC to stop operating. Those are the10A fuses #6, #12 and #19, located in the fuse block (J/B) Picture below. Hope your issue has a simple fix!

 

I had the same problem and at first I couldnt find the fuse because its hard to see unless you stick your head all the way by the pedals its the 10a in the far left bottom corner the #12 spot that was my problem. If that doesnt work nicoclub forums have all the fsm's download ill try post the link.

this is the url to the list of car models. Just selected your car and itll take you to a list of all the fsm's atc is the one youll need.

 

It ended up being a fuse I just checked by eye and was blown but didn't look blown.

 

So you going to buy a new one now? At lease an auto store will have that fuse you'll be looking for.
