No power to the radio, Checked all fuses under, drivers panel, and passengers panel. I have my codes but without power they are useless.

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?

Radio theft protection page 372 owners manual
Your vehicle's audio system may disable itself if it is disconnected from electrical power for any reason. To make it work again, you must enter a specific five-digit code with the preset buttons. Because there are hundreds of number combinations possible from the five digits, making the system work without knowing the exact code is nearly impossible.

If you have no power to radio at all you may need to check all the fuses I do not see a fuse labeled radio but you have 3 fuse boxes.
Drivers side, passenger side and under hood.

Sorry I could not give a exact location.

Locate the fuse box. Use your owners manual and look for fusebox in the index.

Sometimes it is under the hood/bonnet and sometimes it is under the dashboard in the passenger cabin.

It can be mounted under the driver's side or the passenger side. It may also be mounted beside the door A-pillars.

When you remove the lid or cover, look inside and there should be a guide that identifies the location of each fuse, what is protects and its rating. You MUST replace the blown fuse with the rating specified on the guide, NEVER one of a higher rating.

Also, there may be an 'in-line' fuse between the fuse panel and the radio unit. This will be in the wiring loom between the fuse box and the radio. You may have to move the seats back to get access to under the dashboard. This is usually a euro fuse (colour coded) or a glass fuse 1 1/4" long. Always replace this fuse with one of equal rating - NEVER higher rating.

Sounds like you got the wrong pigtail when installing the radio as all those lights go through the radio system which makes it ding reminding you to turn them off when you go to exit the vehicle

acc and radio are on different circuits. Don't just check fuses, but check voltage at fuses - use a small multi meter and test at each point - including at the radio. I am guessing there is a relay for these in the relay box and it maybe malfunctioning.

Maybe you problem is with the switch, or check if power seat circuit has the regular fuse or rather one of those thermal ones.
Passenger compartment fuse panel
The fuse panel is located on the left hand side of the instrument panel facing the drivers side door.

Position 18 25A - Drivers Unlock Relay, All Unlock Relay, All Lock Relay, Power Seats

look for more fuses.check under dashboard,driver and passenger kickpanels,side panels on dasboard.it has to be a fuse that burned out.make sure that you checked everywhere under the hood cause sometimes there are a couple of fuse boxes there.hope this info helps.take care and good luck, manny

You have all the fuse locations. I have seen some that after radio was put in did that. usually it turns out that re-grounding the dash or using different power supplies for the radio has corrected it. otherwise, I'd check the light switch and make sure it's OK.

There are three fuse boxes - Driver Side Instrument Panel, Passenger Side Instrument Panel, and engine compartment (drivers side nearest to the firewall) - The Instrument Panel ones can be located by oning the respective doors and you will find the removalable panels on each end - on each panel door is a guide as to what fuse is located there ---(Radio Fuse is located on the passenger side)

Well I just found my solution.... I was a little too quick the first time.
There are 3 fuse boxes for the 2004 Pilot. One on the drivers side, one under the hood, and one on the passenger side. My 15 Amp fuse on the passenger side (fuse #9) was blown thus causing the front AC outlets and the radio/clock/CD player to be completely dead. I pulled the 15 Amp spare from the fuse box under the hood, and replaced the blown fuse in the passenger side fuse box. The radio came on like a champ and I didn't even need to reset the radio code. I figure I just saved at least $100 vs. taking it to a dealer. :)
