The radio will stop operating and the air conditioner will blow at its highest level. You do not have any control over regulating the temperature or flow. Obviously, I'm not the only person to encounter this problem.

2003 G35 sedan central console a/c, selected lights, and audio controls stopped working suddenly. Cannot control heat/defrost/air conditioning. Caused windows to fog up quickly impairing visual field while driving on highway. This is very hazardous because of its unexpected and unpredictable onset.

There is an apparent known defect in the 2003 Infiniti G35 models. The radio and climate control will apparently lose all indicators, as if there is no power, but will continue to function, staying frozen on at their last settings. The radio volume or channels cannot be changed and the air conditioning/heater,etc. Are stuck on their last settings and cannot be changed without turning the car off. This is caused by a defective control board behind the dash. Infiniti/Nissan is aware of the problem, and has issued a voluntary service campaign (# itb03-007b) to repair the 26,300 vehicles listed by VIN # on the service bulletin. This is a hazard , as in the winter, the front or rear defrosters cannot be turned on, or the air conditioning turned off, causing a hazardous driving condition. Infiniti says my 2003 VIN # does not fall into the bulletin parameters, (VIN # is higher), and they will not cover the repairs, even though it is the same problem. Infiniti states the cost to repair. . . . . . . . . $2600. 00. I have 2 other friends that are having the same problem with their 2003 G35 Infiniti's, also not covered by the service bulletin. It is apparent that the bulletin did not go far enough to cover this defect on a larger quantity of vehicles than Infiniti wants to admit.
