04 TL power draw on #7 backup fuse please help

I have a draw I narrowed it down to the power mirror control module so I went to the junk yard got another one plugged it in and the draw went away, so I put the car back together again and checked and it's back on the power mirror module again any ideas?

You're going to have to go past the power mirror control module. Have you confirmed it is not either of the mirrors or the mirror switch?

It would be easier if you had a low amp probe so you don't have to dig out the all the connectors. You would be able to just clamp on every wire and see which is drawing current.

If that fails, disconnect the power seat control unit and check if draw is gone. Seems like mirror cu communicates with power seat cu. Maybe something is keeping them awake?

Yeah, I forgot to mention that in my post.

Anyway, I did notice the power mirror control unit is not connected to the BCM. I guess the Driver 1 & 2 mirror settings are sent by or through the seat control unit.
