On some model year 2003 G35 Sedans manufactured through August 21, 2002, the audio and temperature controls may not operate as expected. When using the audio equipment or the temperature controls, the unit may become inoperative. In some cases, this can be corrected by turning the ignition switch off and back on again. In other cases, the unit remains inoperative and requires service by an Infiniti technician. To prevent this condition, Infiniti has initiated a Voluntary Service Campaign to replace the audio finisher circuit board on these vehicles. Use Infiniti Net to confirm if a specific vehicle is affected by this service campaign (P3104).

 

I am having the same problem guys! Do you know if you can buy the circuit board somewhere online? I searched and no luck!

 

Circuit board might not always solve this, I had to change my whole head unit. Check ebay for some used OEM head units

Damn, this just happened to me tonight. =(

 

Just happened to me as well. Can anyone confirm that a dealer has repaired this out of warranty at no charge? TIA.

 

Out of warranty? You're probably SOL for a free repair.

 

There's a voluntary recall from Infiniti for this. That's what I'm referring to, not as a warranty repair.

 

That recall only covers certain VIN ranges. If yours is in that range, then you may have a chance.

 

OK, it's NOT a recall, but a service campaign, so even if your VIN falls within the range, it's not covered out of the warranty period.

 

it could be this sensor next to the red circle if you did a double din install...



seen above the red circle here...



many times it is not plugged back in properly...
