I have 2004 SRX V8 and the battery keep on draining after being parked for three or more days. I took it to two dealers and I got two different answers. One said that the battery is not holding the load test. The second one said that the Amplifier drawing .50AMP and they had to pull the fuse to stop the drainage. then I took it to another electrician, and they said it is the Remote Door Lock Receiver ( Antenna Module). Since I got three different answers, I am hesitant to make any repair becuase it raising some doubtsabout their finding and I am not sure if it will fix the problem.

I was told by the dealer that fuse box for the Amplifier is under the driver rear seat which I could not lift up to reach the fuse box. Is ther any trick to it?

Anyone with this experience want to share their resolution?
Thank you
