Defogger Heater Problems of Infiniti G35

My problem is with the dash, where the heating controls and the radio controls are. When I am driving, the heater and radio controls just cut out. It gets very dangerous when it is raining, because the windows will fog up, and in the winter it gets very cold. . . . . Updated 04/02/15.

The defroster, ac/heating system, radio, and selected lights on the dashboard fail randomly, causing the windows to fog in certain weather conditions, making it quite hazardous to drive. The system will automatically turn on, then the fan cycles to higher speeds about every 20 seconds. The heating/air system will become completely uncontrollable, rendering all defrost controls inoperable. During this time, the radio display turns itself off, and all controls on the face of the unit are disabled. The stereo can still be controlled by the steering wheel controls. All button lights remain off, while the center display, located just below the windshield, remains on. There has been a recall for the sedan version of this year/model vehicle for the same issue. The following is the service campaign number for the sedan recall: itb03-007.

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.

A/c came on randomly at high speed,,could now turn of,,fog my windows will my niece was in back in her baby seat,,I tried turning the fan's off,,could not turn of,,and heater and cd malfunction together. Went to dealer they would not replace,will cost 1300,,it was electric problem. I always keep my car up to service.

A/c controls/electrical failing on vehicle. . . During summer months do not have ability to lower a/c (blows hot air). During winter months do not have access to heater or window defroster creating road hazard and personal safety issues. 2003 Infiniti G35 couple.

The heating/defrost/ac unit stops working while driving causing window to fog up during cold weather - back seats are ripping, like brittle. Brake light in back window goes off and on, works when it wants to.
