Have had this problem since I bought the car.
The PO didn't tell me about it.

Finally got around to messing with it.
Pulled every fuse, nothing made a difference.
Went back under the hood, pulled the four fuses going to the SJB (#59, 62, 63, 67).
Drain went away.
When I put either 59 or 67 back in the drain comes back.

Did a search here and found a couple threads, but they ended without a fix.

Thought maybe I need a new SJB but looks like they are discontinued.

Anyone else having this problem.
Do you have a fix.
Are new boxes available, or can they be repaired?

Freind of mine said sell it.
Don't really want to, plus I could not sell it with a known problem.

Thanks

I’m having this problem. I took the SJB out and couldn’t find anything obviously wrong. Everything seems to work, and why install a used box from salvage? I’m going to install a battery disconnect relay for now.
