If you have power to that fuse box then move to the inside fuse box. That thing is called the SJB (Smart Junction Box). Check for power coming into it and then check for power coming out of it. Found a reference to it online, a new one is/was expensive and it looks to have to be programmed by dealer. Maybe the connection is just borked up.CircuitBoardMedics might be able to fix the SJB and would therefore not need to be programmed by the dealer again.</blockquote>
