Infiniti G35 Head Unit *Potential* Repair 

Can't thank you enough for posting this video. I bought a 10$ soldering iron from Wal-Mart, removed the unit, soldered the contacts listed below and everything works like new. All my radio and ac controls are back. For anyone with a G35 looking to fix this problem....take it from me, it works!

Thanks Quantron, This fix really works. My 03 G35 Coupe has been acting up for years. It had finally decided to blow AC at 60 on high. That's OK for Florida, but annoying. Pulled the radio, found the 3 resistors. None appeared loose, but re-soldered each point and the 2 on the power transistor and now everything works like new. Without your research and video, this would all be a proprietary fix for some electronics shop.

Does this fix radio not turning on and ac staying on??

This worked for me, 100%

I will be trying this very soon and I'm confident it will work. Very hopefully it does and I'll update on result.

Did you buy chance find a guide on how to rebuild it? Also like the other folks said did all this work to fix the unit and issues it caused?

My 2008 m35 radio went out yesterday and my a/c won’t turn off I have no lights in the whole center

Worked for me perfectly! Thank you. My issue was similar with the radio display not working, the AC stuck on, but the steering wheel controls working. Here are the two videos you need to see: Infiniti G35 Stereo Removal, Audio Finisher, AC - REPAIR 2003-2004 to see how to remove the stereo unit. Then your video to see where resistors r509 and r510 are which did need to be re-soldered. I watched both, had a friend assist and it took us about two hours. We also had a good quality electrical soldering iron. When he touched r509 and r510 both resistors were loose. We were not sure it was going to work but a little solder and when we reinstalled it was exactly the cure. I can't believe that Nissan / Infiniti didn't warranty this Clarion part. Really poor customer service. Hope this helps you.

does anybody know if replacing the stereo with an aftermaket stereo like pioneer or sony will fix the problem

Thanks a lot. I worked for me also. I solder 508, 509, 510 resistors and it is working perfectly! I did not have to do the last part of your video that it looks Frankensteinish to me! :) Thank again. G35 2004 sedan Bose with navigation.

Update: fixed my ac/heat going in lockdown mode on my 2003 g35 coupe. But my radio is still intermidantly not working. Better than it always not working i guess. Seems to usually be in the mornings when its cold. But ya give that resistor a wiggle and see if its loose. Try to get it proffesinally saudered because its tiny and pretty much almost impossible to get in there unless you have a tinySauder gun and small hands.

Thanks quanttrom. I re-soldered 08, 09 and 10. Thanks so much for taking the time to make the video. Needless to say I could never have figured this out on my own. Now my radio, heating and A/C work thanks to you. BTW, only 508 was mechanically loose.

Does this fix the issue of rebooting

will this work on a 2012 g37

I like the Ellie Goulding in the background lol

This video describes how to fix the 2003 g35 issue where the climate and stereo both stop functioning (the panel in the center console no longer works - so the climate control is stuck wherever it was when it got stuck, and the stereo may only get radio when using the steering wheel controls. I followed the instructions here and re-soldered the 3 contacts (R508, R509, R510) and everything is working again! Thanks to the poster for sharing this video! There's another video that describes how to remove the stereo (which was great to get this unit out of the car).

Just wanted to say thank you for this video - never soldered anything before but gave it a go (508 was very loose) and everything works again! Amazing.

What if the soldering for R509 and R510 are making contact, will it still work?

Any idea for an 05 m45? Getting the same issue but it’s a different setup from the 03’s.

Dear people! Did he change 2x resistors to a single 10 OM at 7:19? Can't such act lead to a bigger trouble?

My Strereo is on and everything kinda works. It doesn't play music, and when it does it's could be staticky or clear but might fade away or not play at all. When I turn up or down the volume the speakers won't make a noise, I know the speaker are fine because it plays clearly when it does. Sometime when the power is on, it will make a sparking noise. Do you know what wrong with it and would it be an easy fix? I justfinished battery and charging at my school so I know the basic of electrical

Glad I found this video before bringing it to the shop. I had the Radio and Climate Control issue where it doesn't respond and I constantly get Auto AC. Tried this yesterday, the resistors looked fine to me but I soldered it anyways. Put everything back and it didn't work, not sure why. I tried it again today, I added a bit more solder to R508,9,10 just in case and also added some solder to the transistor. I was also very careful with the ribbon cable and it fixed it today! Huge help, thank you!

Where can I pay to get this fixed I’m in the New York area

Quantrom, can you give me some insight on the Aux install on your g35? I saw the pics but theres no description of whats happening. Thank you

It really helped me with my car so of the air condition in radio problem thanks it was really really helpful 👍

my g35 navigation screen doesnt turn on anymore but i can see it works fine in the day light its just the background light. anyway i can fix this problem?

I have this problem but the radio i have isnt the original one , should i still try ?

thank you thank you thank you thank you thank you !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

thank you so much, cant believe nissan/clarion dont put out helpful information like this ffs

Thanks for the share, that worked for me. Just a caution when re-soldering the resistors, they will fly off the board, they are a bare to put back in position. Do one side at a time. All is working as normal. Air & heater, radio and all controls working again.

How can I contact you , I have a fx35 04 with same issues

hi so did this fix the drainage issue u had, why do these resistors effect drainage of the battery - please explain... thanks

i'm about to try this right now although i have no tools for the soldering any ideas where i can find them or what i can use ?

thanks to this video helped me solve my problem. keep up with the good work bro

So do you use the same resistors or were they replaced, mine g has this issue, I'm super stoked to take it apart, hoping it works for me as well, great vid btw, you seem to know your shit bro

I have an fx 35 and I want to know if it works as well for that

Hey, I just wanted to say thank you for posting this video. I re-soldered the contacts that you pointed out and everything is working normally again. If it wasn't for you posting this video I would have had to spend alot of money to get it fixed. Thanks again!!

Where do you buy that piece??

My fx 35 04 has the same issue , will the same repair work ?

Does replacing the whole car radio by a new one fix it ?or will it affect the new one as well ?

Hi!!! Do you have any idea how to fix model CLARION PP-2665D-A which was installed in my 2005 g35 coupe? I can't find 508-510 resistors :/ Do you have any scheme to that radio?

does that thing also causes no sound from your stereo? my head unit will turn on and everything is working perfectly, but there is no sound from my stereo and im not sure if its a wiring issue too because its a stock bose stereo so all the wiring is compacted with all the other wires so if its a wire problem then i should have problems with other parts of the electronic too, but im not. sometimes when its cold outside and the next morning i turn the car on the sound will come on right away after a cold night then sometimes when i do manage to get the sound working only the back speaker is working and often the volume will be stuck on a specific volume and i cant change it lower or higher. then sometimes i will set the volume to a specific level and turn the radio off and on and the volume will jump to a lower level instead of staying at that specific volume level i set it too. i already check the AMP and head unit and everything seems fine by looking at it. i haven't crack open the Head Unit, but i did on the AMP and everything in there looks fine. check the grounding and its good. so im not sure no more. *2004 G35 coupe*

If I get a new battery will it fix the problem?
