2006 Odyssey driver side sliding door will not latch, even in manual.

Initially the door, while driving, would occasionally beep while driving. Ended
up getting to the point where when we tried to open the door electronically it
would make around 3 loud, harsh click/beeping sound and the door wouldn't
open. I did the fuse pull, door reset, easy fixes and nothing worked.
(Sidenote: During this time the passenger side had no issues).
We started having the battery dying overnight issue so I'd pulled fuse 7 and
we were using the doors in manual mode. I ended up going to Pull a Part
and getting a new rear latch assembly and installing it. When I went to close
the door now the door won't latch at all and even after resetting the doors
again, it's like there's no power to the latch assembly at all.
I put the old one back in to see if would at least draw power, and nothing.
I'm super frustrated and hoping any of you guys might have a suggestion.
I've read through a lot of threads, but I can't find anything specific to this one.
Even in manual on the passenger side, when I trip the latch it'll close (you
can hear the motor working) then release when I pull the handle. I've gotten
the driver door to latch a time or two, but most of the time I can just close it,
then open it right back up without even using the handle. I'm stumped.
Thanks guys!
