I've had a recurring problem for the past year - and I've already spent too much on false leads. It's an '03 sport sedan with automatic. Only 33K miles. I love everything about the car, but this! I have a substantial parasitic drain on the battery. If the car sits for more than 24 hours or so, it drains the battery completely. I've been told the battery was too old and not holding a charge. Replaced the battery - w/ no effect. Later told there was a short in the trunk release switch. Replaced switch - to no effect. At this point - my CD exchanger failed. It seems to have developed a mechanical problem - and a microprocessor in the system burned out. Replaced the microprocessor and CD exchanger. At first, we thought this might have been related to the electrial problem, but after the repair, the drain remained. [Note, the work on the CD exchanger was quite involved. Not even the dealer would touch it. Had to disable the airbags and remove the dash to get at the system.] The drain was tracked to the circuit which controls the radio, HVAC etc - but we've tested all the lines shown on the schematics that run off this circuit. Now at a loss - where else to look. I presume their are additional lines off this circuit - but without knowing where to look - its like finding a needle in the haystack.I've seen references to another radio circuit board - but not sure if that is my problem. All systems on the car seem to be functioning. I'm taking the car back to the dealer next week and would appreciate any further guidance to help direct them in the search.

Replying to: ema15 (May 08, 2008 8:14 pm) ITB03-007b VOLUNTARY SERVICE CAMPAIGN 2003 INFINITI G35 SEDAN; AUDIO FINISHER CIRCUIT BOARD On some model year 2003 G35 Sedans manufactured through August 21, 2002, the audio and temperature controls may not operate as expected. When using the audio equipment or the temperature controls, the unit may become inoperative. In some cases, this can be corrected by turning the ignition switch off and back on again. In other cases, the unit remains inoperative and requires service by an Infiniti technician. To prevent this condition, Infiniti has initiated a Voluntary Service Campaign to replace the audio finisher circuit board on these vehicles. Use Infiniti Net to confirm if a specific vehicle is affected by this service campaign (P3104).

| Ok i was working on my 04 infiniti G35X sedan. I am fixing all the rattles and all the vibrations. I really love this car and take extremely good care of it. This was an accident. this is what happened. I opened up the front passenger door panel unscrewed it and lifted it up and away. i didnt disconnect any wires. i got a wrench and was tightening the bolts. as i got to the bottom of the door i saw a little blue light go from the wrench to the bolt and all the interior lights the vanity mirror lights, the map lights, the door lights, and rear door overhead lights went out as well as the trunk light. I replaced the fuse in the fuse box. Can anyone please tell me what the problem is i want to fix it without taking it to my INFINITI DEALER. They will charge me a fortune. PLease tell me if i can repair it myself. And how much it costs to do so or if you have any tips. I live in miami FL, so if you know any good cheap auto lighting places please let me know. Thank you. | |

| There are threads on the Forum referring to 2003 and 2008 electronics freeze-ups. I discovered today that Infiniti is shipping a large number of control boards for 2008 vehicles experiencing nav, audio, and climate freeze-ups. There are so many dealer requests for the control boards that there is a production/shipping backlog of about 4 weeks. The freeze-ups may be effecting cruise control and outside temperature readings, as well. Check with your dealer about a possible Service Bulletin on the freeze-ups. While waiting for the replacement part, you may be able to re-boot the system by turning the ignition off and on a couple of times. This isn't a permanent fix, but restores the system to temporary operation. | |
