Question about Infiniti G35

2 Answers

Battery drain I have a 2004 G35 with an intermittent battery drain issue. I can not determine any common factors and it might be 4 months between events or happen 3 times in a week. When it happens, the battery is completely drained within 4 hours (clock, radio, etc.. all reset) and car will still have power, but not enough to turn over after 2-3 hours. The battery has been replaced 4 times in 3 years due to failure from multiple events. I have had the electrical system tested several times, but everything was perfect with no drain and it doesn't seem like a normal short as everything is fine when you jump the car to start it (like it resets the component causing the drain) - so a drain test when it goes dead doesn't show anything. I have replaced the radio as many had issues with that (as this car did). It seems like it has to be something that is between the battery and ignition as it happens when turned off, but there are no sounds, no lights on, nor any evidence of abnormal behavior until I try to start it later. Any thoughts?

Feeling what you're doing with his hey relay or circuit breaker sticking between contacts every once in awhile it will stay on possibly your faN relays as these relays keep power to the fans as needed until temperature reaches optimum shut off timemeaning that once the vehicle is turned off if the temperature is still high the fans will continue to run even though the vehicle is turned off

SOURCE: battery goes dead on 2004 pacifica

There is obviously a draw from somewhere, and if your dealer doesn't have a mechanic who knows how to narrow it down to the circuit causing the problem, then I'd question there ability. With that said, when all else fails, you simply remove negative connection off battery first, then positive. Take a 12 volt test light & secure one end to the + clamp or connector, and the other end to the battery+ post. Now connect your negative back up to the battery as it was. If that test light, lights up, there is a draw. It will be brighter, the more draw there is. Your going to have some, just from your radio memory alone, but now comes the fun part. All you do is pull the fuses one at a time, if light goes out, or dim's you've found a draw. When you have a real hard one to narrow down, you make sure you know where they all go back to, whether by your map at fuse box, or your own notes, and you pull them all out, and light should go out for sure, if not, there is another circuit or panel, or relay drawing the current. If it goes out, you start putting them back in one at a time, and when the light comes back on bright, you found the circuit. Mark that one down, pull the fuse back out, light off, now do the rest that you haven't checked yet, just to see if there is more than one draw causing the problem, if there is, mark it down, pull it out & continue on until all done. Now you/they narrowed it down or isolated the circuit causing the problem.

Try cleaning the battery connectors at both ends and make sure the ground at the frame is clear of rust. If that check out, drop the starter and have it bench tested

SOURCE: 2000 Navigator - something draining on battery - goes dead

Hellokrissypoo4...Your navigator has what is known as a parasitic battery drain...meaning, something in the vehicles system is not turning is the way i test for this, you will need a digitial multimeter to perform this test...when doing this test make sure that the dome light, under hood light, trunk light, etc. are OFF.

  1. Remove the negative side battery cable from the negative battery terminal.
  2. Attach an ammeter(this measures amperage) between the negative cable and the negative battery post. wait a few seconds to several minutes for the car to go into sleep mode. i.e. when you make the contact with the test light the cars computer systems "wake up" after a bit of time they will go to "sleep".
  3. If the ammeter is reading over 25-50 milliamps, something is using too much battery power.
  4. Go to the fuse panel(s) and remove fuses, one at a time. Pull the main fuses (higher amp ratings)last. Be sure to observe the ammeter after pulling each fuse.
  5. Watch for the ammeter to drop to acceptable drain. The fuse that reduces the drain is the draw. Consult the owners' manual or service manual to find what circuits are on that fuse.
  6. Check each device (circuit) on that fuse. Stop each lamp, heater, etc. to find the drain.
  7. Repeat steps 1&2 to test your repair. The ammeter will tell you exact numbers

  8. Some after-market alarm systems may make this test too long or loud to be worth the effort. If that's the case, seek professional help.
  9. In more and more models made after 2003 disconnecting the battery will reset the PCM requiring the modules to relearn. In certain cases this requires a factory scan tool. It is best to take such cars to either the dealer or a professional in auto electrical systems.
  10. Be careful working around the battery in a car
Good luck krissy..i hope this helps..please rate me a fixya.

SOURCE: Electrical Short???

Has the stereo been changed recently? If not move to the cigerett lighter. These two are most likely the prob. But you could have a bare wire anywhere grounding out. Good luck and hope you find it.

Blinkers working intermittently on pontiac 2004 grand am

I believe this is still an old fashioned bi-metal flasher system.the flasher has two metal strips bonded together that expand and contract at different rates,causing the strip to bend.This causes the strip to bend,turning the circuit off.When the strip cools,the strip straightens out and turns the circuit on(this happens repeatedly to flash the bulbs).Because cool tempuratures make it work better,I think the flasher is bad.

2004 g35 coupe wont start. Is it the starter?

Hi there.

Firstly, have you checked that the battery is connected and has a charge in it? (This can be determined by looking to see if the dash lights illuminate when you turn the ignition on).

It could also be your spark plugs/glo plugs need cleaned or changed.

Another thing it may be is if the immobiliser is switched on.

Check all of your fuses.

Failing all of this, then yes, it could be your starter.

Hope this helps.

My new Honda Fit (one month old) stood for 2 days, and I had locked the car with the remote until I hear the horn sound. When I came back this morning the battery was dead. No apparent cause. No light left...

We have two new Honda Jazz/Fit in my family and haven't had nor heard of the same fault.

But it can happen to any car if you make regular short journeys with things like defoggers, lights, seat heaters and similar devices in use as they drain the battery more than the alternator gets a chance to recharge it.

If you know that's not the cause and if it happens again, then you'll know that there's a battery draining fault somewhere. If the dealer then remains unable to trace a fault it may be one of those difficult to trace intermittent faults and eventually your Lemon Laws may apply. I wish we had them in the UK!

Driver side window not working for g35 infinit coupe

This is a common problem on the G35. The window regulator/motor have most likely gone bad. I've also seen a case where the switch was the culprit. Try clicking the switch up repeatedly a few times and see if that does the trick.
