    Would the alternator not cause other problems as well? What is the charging system and how do I check it?

  • arevalor_82 Jan 14, 2009

    I have this same problem on my g35 03. The alternator has been tested and it's normal. Any other suggestions?

    I took my car in for soemthing similar.

    The lights go out in the center panel, G35 sedan 2003 (first model year). Then the buttons no longer work and the air conditioner comes on and can't be stopped since the buttons don't work as the lights are off.

    What i was told is that the radio and air unit, are on the same circuit and it's caused by a glitch in some of the radio units.

    The mechanic himself came to speak to me. he said they've seen in in 3 cars in 4 years so it's not a huge issue but sounds like you and me got some rare bad radio batch or something.

    They ordered radio for me (warranty over so had to pay $400 cdn for it)....and will replace it. It better work ...

    Wow, I have the same problem with my 03 G35 where the radio lights go out and the air comes on( and wastes my gas) and none of the buttons work, and what did the dealer say causes this?

    I have the same problem as starfyrexxx. All the lights went out and then radio and ac dont work. The AC is on but I can turn it off or adjust anything.

  • Anonymous Apr 08, 2009

    same here, the center panel just went dark & the AC just run by itself. 2003 sedan. wonder how many people have the same issue.

  • Anonymous Apr 20, 2009

    I had a "draw" on my battery and was told by the dealer that I needed to replace to radio in order to completely fix that. instead I had them unhook the radio, which is connected to the climate control, leaving me with 72 degrees constantly in my car and no radio or fog control.

  • Anonymous Apr 24, 2009

    I also have a 2003 G35 Sedan which has the same problem. The radio and AC control buttons dont work and the lights go out as well. The car has 95,000 miles on it.

  • O Mclean Dec 19, 2008

    The charging system is run by the alternator it just a basic check of the system. may I suggest an Auto-zone they do it for free they have a portable machine it checks that battery the alternator and even a starter draw. They just bring it out to you car in the parking lot and check for you. I really think its the alternator but I wanted to make sure by checking the entire system, try them it take just a second.

How does the display on my CD/radio work?

Sorry to hear the display is blank even though the cd radio appears to function. The display is usually an LCD with back panel lights that makes the characters visible. Most likely the small rice globes behind the panel are blown. Usually needs some sort of desoldering and resoldering to replace. If you can take the player out from the dashboard and take it to the local audio repair shop you will save quite a bit of money to get this fixed.

I am assuming your CD radio looks something like this.

2002 chevy monte carlo stero problems

The stereos antitheft isnt armed is it. This makes it so the stereo wont work until it is disarmed by typing in a 4 number code for your car. Its only supposed to arm if the power is cut though such as the fuse was pulled or the battery was disconnected from the car.

Service engine soon light is on constantly.

ALTENATOR AND BELT PROBLEMS: I would assume that someone has c hecked the battery. A dead cell will shorten the life of the alternator..If the plug( at the alternator) is the least bit shakey, replace it. Check all grounds, engine to firewall, engine to frame, engine to battery, frame to radiator support, and the alternator plug, again.
CAR STALLS/DIES/LACK OF POWER: Have your mechanic inspect and clean the throttle body and the idle control motor. When these parts get dirty with carbon and debris they will cause erratic idle and dying at stops and low speed complaints.
CRUISE CONTROL AND BRAKE LIGHTS: First, check the obvious. Blown fuses? Check brake lights -- if both are blown, the system won't work. Also look for any disconnected vacuum lines in the engine compartment.
