Dean is exactly right...:thumb:..it's called the IOD fuse...look under the cover of the fuse box and see where it says IOD...pull that fuse and things that are not required to work such as alarm and radio and such goes dead..try that and see what happens...the car will still run...jus some stuff won't work....LenGTS Dean said:The radio memory and clock saps power, along with the alarm. I think there's a fuse you can pull to minimize drain over long periods of inactivity.
