Defogger Problems of Infiniti G35

Ac/climate control circuit board is not functioning. There was a voluntary service campaign issued by Infiniti (tb003-007, campaign id p3104), but only for certain VIN numbers. Many other 2003 owners, not covered by the recall, are experiencing the same issue. This is a safety issue as rear and front window defrosters do not operate.

Driving hazard b/c of not being able to control the climate, particularly the front and rear window defrosters.

Air conditioning/heating controls running full blast with zero ability to control. This is a safety issue as windows cannot be defrosted in the winter. Radio not working. Infiniti corporation is not warranting this issue, but refers customers to local dealerships.

The climate control system malfunctioned. The blower went to the highest level and could not be adjusted using the controls. The display panel for the radio also went blank. Tried to turned everything off but the controls did not work, therefore had to turn the car off. Once the care was off I turn it back on and the fan blower was at medium, and I was still not able to adjust the temperature, defroster or other controls including the radio from the panel. I was able to adjust the radio from the steering wheel. The next day everything began to work. Approximately one month later the same thing occurred lasting about two days before everything began to operated again.

Unable to defog windows because all of the climate control buttons are inoperable. Currently the climate control system is "stuck" at 71 degrees and the radio is completely out.

The audio and temperature controls become inoperable because of a known issue with the audio finisher circuit board. My temperature was stuck at 90 degrees at maximum output, with no possible way to shut it off. There was a voluntary recall for 2003 G35 sedans with this issue (Infiniti recall # p31040), but not for coupes. From online research, there appears to be numerous cases where the same issue has occurred on 2003 G35 coupes, but Infiniti refuses to accept responsibility for repairs, because the VIN #'s were not part of the original recall. I believe this is a safety defect that constitutes a recall for any G35 model with this known issue.

The radio will turn off by itself and turn back on a few seconds later. All of the buttons in the center console become inoperable. The a/c controls also become inoperable and turns on by itself. It just doesn't turn on though, it turns on 90 degrees and starts blasting out. This is a safely issue because as a driver we never know when this air is just going to start blasting out at us like fire. If Infiniti is Smart enough to recall the sedan, they should do the same thing with the coupes. It is clearly a common problem among the '03-'04 models. If they want to keep their reputable name they will do what is right.

The ac/heat controller stopped working. The ac was stuck at full, at 60 degrees which created mist on all of the windows. I was not able to turn on the defroster which made my driving dangerous.

The contact owns a 2003 Infiniti G35. The contact stated that while driving 65 mph, several warning lights illuminated on the instrument panel warning her that the vehicle was slipping into different gears. The vehicle was also slow to respond when the contact attempted to accelerate or when decelerating. In addition, the heat would activate independently and the contact would have trouble turning the heater off. The vehicle was neither diagnosed nor repaired. The failure mileage was unknown and the current mileage was 90,000.

First defect: when I would start my car the lights would go out and the radio, heating and cooling buttons. The fan would come onto high and switch to airconditioning. I could not turn it down or turn it off or turn on my defroster when it was 30 degrees in the morning which made my visibility very poor. The only way to get this to stop was to pull the fuses. We check the recall history and found that it was only a courtesy recall and wouldn't be covered even after reading that hundreds of G35 owners were all having the same problem. We had to have the radio electronics removed from the car and sent out to be fixed. I think this issue would be consisted a safety issue when you don't have heat or a defroster. Second defect: the problem started while the car was idling and it would stall. Then 3 days later while driving at 50mph the car tried to stall and it lost all power and then the dash lights came on indicating service needed. The car seem to lack power. Did a recall check and found that all the conditions pointed to the cam shaft position censor failing. We checked the VIN# and of course my car isn't one that is on their recall list for the same problem they have on other G35 models. This could be a serious safety issue causing an accident when you stall and have no control of your vehicle going down the highway. Every issue I have had with my car has been on the companies recall list but not my VIN # for some reason. This issue to need to reviewed and corrected. Third defect: we have had to have the motor replaced twice in the drivers door that operates the electric window. Now the right door window is not working. If it does open it will get stuck and we have trouble getting it to come up. We have to keep it locked to avoid it being opened.

The audio/climate controls on my 2003 Infiniti G35 stopped working while my ac goes on full blast. Can't turn it off. I have no control of my radio. Called the dealer. They said it could be the radio ($900), the circuit board ($900) or both ($1800) plus tax. And that's on top of the diagnostics fee they will charge. Infiniti service advisor told me that because it's out of warranty, it's just like a bulb going out. What a ripoff. .

I have a 2003 Infiniti G35. The center console, controlling the heater/ac and the radio is not working. I was told that there is a control board problem that Infiniti is not claiming, yet according to the web, there are several complaining of the same problem.

The defrost no longer works. It has short circuited the heat and ac unit. The entire unit controls the radio and cd player. Can't control any of these functions. Many people with the 2003 infinity g 35 have these problems.

The display on my radio started to go out and made it so I had no control over the radio and the ac/heater. It went off and on randomly for the past year, now my radio is completely dead and still have no control over my a/c controls so it blows at my feet. Now that temp. Outside is getting into the 30's, and I need my defrost to be able to see through my windshield but can't control it. . .
