yeah i took everything apart i still have it apart i try conecting just the A/C b
plug and it dont work... did yours work when you only conected the a/c plug?

 

The only solution to this is to bring it to infiniti dealer and they have to replace the headunit chip on your radio. the radio head unit for some reason is connected to the A/C CONTOLS. I had the same problem and took it to the dealer. i have an extended warranty so i have to pay $100. i dont know if u have an extended warranty?

 

my b i meant if u removed them by accident put it back together cause that 5 strip wire will iluminate the radio screen.... here were my cars symthops, i turned it on a beeeeep will go out and then ac came on...nothing came on the radio but i could here the radio and controll it from the steering wheel......


i didnt remove the a/c plug just to let u know ac and radio are somehow connected together its really stupid

 

did you solved the issue?

 

I have the same problem 2003 G35 coupe w bose system. Began as CD ERROR message then intermittent loss of control for the radio. Then AC controls began acting up sporadically. Unfortunately all is quiet no controls work steering wheel controls no he. Currently AC is stuck at 75 deg radio is dead. several blogs have indicated circuit board on AC and Audio Control Panel.

Read a previous posting and it provided this link for a cheaper solution http://www.carstereohelp.com/infiniti.htm looking at giving it a shot wondering if anyone has any feedback on this company

 

i ordered the jdm double din with ac controls im going to see if that solves the proble since it wont be conected to our sorry stock sterio thats making us spend $$$... i get it here on wednesday...so i will come back and let you guys know... hopefully that works cuz jdm parts arent cheap

 

whats up peeps.... i just got in my jdm dd conversion with ac control i pluged in the harness and well...... i have control of my A/c again!!!!! i can turn off now... but i havent drove the car for about 4 days.. i have all my interior off im going to put the double din stereo but im waiting for pioneer to send me a new power cord for my avh 3100 im not sure one i conect it will it get mess up again.. hopefully not.

 

so after almost 2 years of driving around with no cd player and a little over a year of the dash going out i finally replaced the oem cdplayer with another and also replaced the circuitboard and everything is working properly again, for the mean time that is.

 

Just had mine replaced at the stealer. From what I've read, this is the only sure cure. $500 P&L but it works and has a 1-year warranty. Would have liked to go aftermarket but don't trust the local shops.

 

my a/c died and my radio died and my dashlights all died in one day.
i was pissed and the dealership made me get a new radio. i installed it myself and nope
nothing is working still, i just spent almost $300 for nothing
what could be wrong??? the curcuit board maybe/??/??

 

its not the radio, its the circuit board.

 

I have the exact same problem, but i also have navi so a DD conversion is out of the question...this sucks!

 

I tried everything (without replacing parts), nothing work.
Then I got pissed and hit the right side of the radio really hard, well, that fixed it.... Has been working without any problems for a few days now.

 

This is what i been telling ppl! i did the same for mine. Read my last post.

 

Hitting the right side (didn't try the left yet) of the radio fixes this problem.

The radio/AC controls have gone up twice in the last two days, but a little hit on the right side fixes it every time.

I don't think anyone needs to have expensive repair work done, it's probably just a small solder point that needs to be checked.........

Years ago, I had a Nissan 240SX, which completely shut down, every time I drove it for a while and wouldn't start until it cooled off....

I found that it was related to the ECU.. I removed the ECU, opened it up and found that one small solder point was completely gone.... Two minutes later I had that fixed and the car run for long time without any more problems.
