Has anyone seen this before?
My lights on the stereo and hvac controls go out sometimes and come back on later. I can still control the stereo by the steering wheel. When the lights go out on the HVAC I can't control anything but then the heat comes on in the floor position by itself. Same with the stereo, I have no control of it (besides steering wheel) when the lights are out.
It is rather bizarre and when I took it to the dealership for an oil change the lights were on so they didn't know what would have caused it.
It almost seems like there may be a short of some kind.
Any input would be greatly appreciated
Matt

 

its happened to me. did it frequently for a few weeks and now does it once a month, maybe less. Someone told me its the car telling its time to trade up to a newer model. How many miles? I got 72k on mine

 

This happened to me once. I pulled out the corresponding fuse and pushed it back in and everything went back to normal.

 

It is a 2003 and has 101kms. I will try the fuse trick, thanks for the heads up

 

Its the circuit board that controls both the AC and the radio...it has a defect. There was a recall for it.

"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)."

Wow! That is great G35Papa. I will look for it
Thanks again
Matt

 

No problem Matt

 

Its also in the FAQ tread try doing a search

 

I actually DID do a search but I didn't know it was called the audio finisher circuit board. So what I do is list my symptoms and hopefully someone may have an idea what I was talking about.
Thanks to everyone who responded (especially G35papa) because I have tons of info now that I know that it is called the audio finisher circuit board.
THAT is when I used the search function.

 

its either the audio board or the actual CD changer unit. it could be either. you will need the part number if your planning to get used. they are different in different models. ie. SAT botton, etc

 

Good to know, thanks a lot!
