You need to locate the source of the noise and find out which component is causing it.
It could be a motor, relay or solenoid.
If possible, get a scan done to check for trouble codes. Take note that scan tool must have all control system diagnostic capabilities, normal code readers would not work.
Keeping the fuse in and if it is a motor running, it would definitely drain the battery.
