2007 Expedition battery being drained

I have a '07 Expedition with a battery drain. Hooked a meter up to it and after a couple mins the meter will show the truck is in "sleep" mode with a low mA reading. About every 30 secs the meter will jump to between 7-9 Amps for about 3-5 secs then back down to a low mA reading. Cant remember the actual low number, even reading 0. Even before the truck enters "sleep" mode the same cycle is going on, just the mA aren't as low of course. I'm thinking this is the smart junction box, but didn't have time to stay at my friends house using the meter to pull fuses. Also I was trying to find out what fuse number the SJB is. Any help please? Or ideas if I'm on the right track. Thanks!

Had a battery drain on my 07, turned out to be the rear wiper motor, common problem.

Fuse 19. I figured out my problem. I knew the rear wiper didn't work but the motor did, or tried to. When I would pop the rear window, the wiper motor would cycle then park. The the battery would not drain any more. Pulled fuse 19 until I could fix the rear wiper.

Fixed the rear wiper this evening. Search for rear wiper in this section for details but I basically removed the rear wiper arm, disassembled the pivot arm from the assembly, cleaned all the parts and reassembled it. Wiper works now.

Poor design allows grit to seep into the assembly and cause it to seize up.

Good luck!
