I have an Infiniti G 35 2003 and I cannot adjust the temperature settings or airflow nor does the audio equipment work


Common issue with the 2003 Model G35. The culprit is the radio/HVAC circuit board. Unfortunately, since the OEM radio and HVAC system is integrated, it means replacing the entire circuit board which can be pricey. Google "Infiniti ITB03-007" for more information.

Describe your Infinity RS-12 Subwoofer parts Problem. I have a Buzzing sound, I believe that one of the RCA input jacks is bad from the use of a POS Monster Cable that was hard to plug in. Broken the RCA...


Do you know for certain it is broke?
Could you have just damaged the soldering to it. RCA jack sockets are easy to get hold of at electrical parts shops such as Maplin (UK) or Radioshack (USA) or the like... You might just need to take it out to show them at the shop.

Infiniti G35 speakers don't work


03 and 04 G35 vehicles had a Technical Service Bulletin issued regarding the audio circuit board. No sound was one of the symptoms of a faulty circuit board. There was a design flaw with the boards on the early model G35's that was corrected in 05.The audio units on those cars consisted of three pieces, the radio itself, which is just a silver box, a circuit board that attaches to the front of the radio and then the outer display. I would suggest contacting a dealership service dept. with your VIN number in hand, and ask if the circuit board has been replaced. Even if it has, It will still more than likely be the problem. It's either that or the radio

I have a 2004 infiniti g35 and the speakers don't work... howevr the cd and radio console works just fine i just don't hear any sound at all? does any one have the same problem?


03 and 04 G35's had a Technical Service Bulletin regarding the audio system circuit board. I would suggest calling your nearest dealer with your VIN number in hand and ask if the Circuit board has been replaced. If it has it could still be the issue. The radio unit itself could be bad too. I worked for an Infiniti dealer for 10 years and we replaced a lot of circuit boards, and quite a few radio units. On those vehicles, however the radio is not like the radio on most cars. The display is one part, connected to the console, behind that is the circuit board and behind the board is the radio, which is nothing more than a square silver box. More than likely this is going to be a dealer only repair as is the case with most of the newer Infiniti models.
