I replaced my battery twice only to find out there was something draining the battery. Took it to a shop and was told he was not able to fix. He suggested I take it to a dealer who has the equipment to analyze the problem. He also indicated that the drain was comming from the BCM at a rate of 8 volts.
Before I go to a Dealer maybe someone here can help or advise. I just found another problem, the trunk won't open from inside button nor will my remote open the trunk. But it will open by key.
Thanks

an 8volt draw does not tell you anything.... you need to know how many amps you are drawing... open your pass thru in the rear seat and make sure that your trunk light is not stuck on.... if not you have to hook a meter in line on the power side of the battery....measure the amount of draw with every thing off...I'm not sure what the limit for nissan is ....should be less than 0.1 amp

 

Thanks, I'll try it.
