Infiniti G35 Electrical Issues



  • ragu1ragu1 Member Posts: 1
    Hello. I am having a similar problems. All the lights on the control panel are off, the buttons and radio don't work, and the A/C controls itself. The Infiniti dealer quoted me around $700. I'm a student, is there a cheaper fix that will fix the radio and the air conditioning.

    Also, I am located in Columbus, Ohio. Has anyone gotten this problem resolved in Ohio?

    I've been experiencing this issue for the past few years. A/C would go full blast, the radio would only be accessible through the steering wheel. It would do that for a few minutes/hours, sometimes even a day. Then it would go back to normal. Recently, it hasn't.

    So I started strolling the "interwebz" for solutions. I did the obvious and changed all the corresponding fuses and still nothing.

    I called Infiniti Consumer affairs and gave them my VIN number, unfortunately, they told me that this wasn't covered under a recall at least for me and my extended warranty has expired.

    So I bit the bullet and called the dealership. They were aware of the problem but quoted me a price of $600 to repair it. Now my car is almost 10 years old and wasn't really looking into putting $600 minimum to replace it.

    So I looked around New Jersey for places that could possibly repair it. Each place wasn't necessarily aware and were hesitant to do any work on it.

    It then dawned on me, what if there wasn't an issue and I just wanted to replace my radio? So I called the dealership again and asked what the $600 covered and was informed a new radio and that the wiring for the AC ran through the radio. I then pressed them, well, what's to stop me from just purchasing a new radio from Best Buy. Then said, if they wired it through the stereo, there shouldn't be a problem.

    So I called Best Buy, and they said, they could replace a radio in a G35 and were cognizant of the AC wiring. However, I would have to purchases some additional materials, wiring and a new face plate for my stereo.

    I purchased the Metra Kit, antenna adapter, and the amplifier integration harness through Amazon.

    I bought a $90 stereo from Best Buy. Cost $50 to install it. With the previous purchased and a couple of new parts, it totaled a little over $325 for everything.

    Air conditioner is controllable again and the stereo works great.

    Only think is the new buttons for my air conditioner look a little "cheap" from the Metra kit.

    Otherwise, I'm happy. I paid about half of what I would have paid going to Infiniti.

    I have had to remove several posts lately that contained phone numbers. Please don't post ANY contact info in the forums - this is particularly important when the contact info doesn't belong to you.

    You can post a name and the name of the company - let people google for the rest. Thanks!

    So Do You Think I Will Have Electrical Problems After I Install My Doublin Din Interface with The Double Din Radio For My Infiniti G35 2003?
  • rachel80rachel80 Member Posts: 1
    I have the same issue with my G35. Can you please share with Best Buy you went to? I live in NJ as well. Thank you so much!

    I had a center stack inoperable problem (off and on) for years. The dealer was no help. They wanted $150 to tell me how much the repair would cost. Crazy, right?

    I finally found a guy on eBay who would fix the problem for $160. All I had to do was remove the radio and send it to him. But, as it turns out, we're both in LA so I drove to his shop in El Monte and he fixed the problem for $200. ($160 for the repair, $40 to remove and re-install.) In and out in under an hour. No aftermarket parts needed.

    Before I left I asked what the problem was. (I'd heard it was a bad audio finisher board, but that's not right.) According to John, the guy who fixed it, some solder connections fail and kill the power. Which kills the power to the HVAC controls as well.

    I had it done today and so far so good. It came with a 90 day warranty.

    You can reach John through eBay (member xw1600) or [email protected]

    Or, if you don't live in the LA area, you can probably find a competent radio tech to do the same thing.

    I hope this helps.

    BTW, I just read the message a dozen replies up about the same guy.

    What year is your G35? I am considering buying a 2006 G35, what is your take on this?

    Thanks, if you are still available on this site.

    I think there's a problem in your battery.

    It sounds like a lot of us have the same problem. I also have a 2003 G35 infinity. The controls went, the ac is stuck on. I can only control the radio from the steering wheel. I found that there is/was a voluntary service campaign ITBO3-007b, Audio Finisher Circuit Board. It costs $1,500 to repair at the dealer. When I dropped the car off at the dealer, he said it wasn't covered. I call Infinity's consumer affairs line 1-800-662-6200. I was told that my car's vin was not listed. There was nothing they could do. Now, I see this is an ongoing problem for a lot of us. It would be great if you all could call and report your issue, maybe infinity will take notice. I feel that infinity still has a problem with the Audio finisher circuit board, Infinity is aware of it and will not correct it. Anybody have any other suggestions for me?

    Hi vfr0092,

    I need to repair my 2003 G35 which now has the AC on full blast w/o any way to control it nor the radio.

    Did the "fix" from 2009 work long enough for you? I am considering that same fix versus a new car stereo.

    I got my fix over a year ago and so far no problem. And I got it fix for $300.

    Hi Dungster1,

    Where/who fixed it for you?

    I am in Dallas and don't know if there is any G35 gurus to do this. I did see the Florida outfit (Factory Car Stereo Repair :

    Hi All,

    My electrical problem with the radio/AC controls is Fixed! WOOOHOOO! All for under $225. Compared to the dealer's quote of $1,500. I went with the fix on post #153. My husband removed the radio, with the help of you tube. I sent the radio to Nahhed at Electronic Masters in Deluth, GA. (Need to send a money order) Received the radio back about 1 week later, installed and is working just great! Great timing since the weather has changed and I don't need the A/C cranking in my face anymore.

    Many thanks to all you, I couldn't have done it with out you. :)
  • relaxtimerelaxtime Member Posts: 3
    Thank you for sharing. My car is all fixed. I got the radio back today, installed and works beautifully. It cost me $225, Naheed went down on the price. He must have so many of the g35 radios in stock! LOL. I am so happy especially since the dealer quoted me $1,500. Thanks again.

    I am new to this forum so possibly this has been asked and answered before.

    I am having the same electrical/AC problem with my 2003 G35.

    The solution in Post #452 sounds great. Does anyone know where I could get this done in Canada?
  • canadag35canadag35 Member Posts: 7
    If you are in the Toronto area, I know where you can get this done. I had my done for $300 in one hour while I waited. I need to check my invoice as I don't recall the name of the place at the moment. If you're not in Toronto, it might not be that helpful.
  • jim590jim590 Member Posts: 2

    I don't live in TO but I go there a few times a year so if you have the time I would appreciate the name and address where you got your car fixed.

    Question - for me I have the issue of both the center console (navigation/radio) that froze the other day, therefore debilitating the air and radio feature. I turned my car off and back on and it went back to normal. But... prior to that i'd first noticed the speedometer area's lights had started flickering and turning off in areas - so the combination of things really started to worry me. Does anybody knows if replacing the radio solves both the console AND flickering dashboard lights issues or are they separate problems? Thanks!!

    when you hover over the QUOTE/LIKE/LOL, there's a post# in there. Otherwise, if they're referring to a different post count, I think there's ~30 posts per page.

    So, my 2003 g35 sedan only started experiencing this issue 2 months ago. I have less than 50K miles on it because it was driven very infrequently prior to 4-5 years ago.

    My dealer quoted me $1500 to replace both the audio board and the radio (refurbished).

    Anyhow, I've read through all these 15 pages worth of posts ... is the replacement choices below any different if the car has the NAV system?

    I see my options really as being the following:

    OPTION1 - replace with unit from john huang for roughly $250 before crediting the return (xw1600 on ebay) --

    Question - has anyone who's replaced it with one of his units had any issues if you've had it 1+ year?

    OPTION2 - Get the metra kit (PN 99-7604), Amp Integration Harness (70-7551), Antenna Adapter (40-NI20), PAC ROEMNIS2 (2003 model only, factory premium sound interface) and a radio/deck of my choosing. I see this as the most expensive option ($500-700) but it should fix the issue once and for all.

    Question - Does my built-in NAV require a different metra kit or anything? I couldn't see anyone definitively talk about it in prior posts. Or is the NAV completely separate from the radio/ac control/etc?

    OPTION3 - bring the unit into a Clarion service station and have them replace it with a refurbished unit as someone else mentioned which has upgraded electronics to fix this issue.
