Honda Civic single power door lock not working

good day!
I have a 2003 DX-G sedan
My driver’s side rear door power lock is not working.
the lock works fine manually (meaning the mechanism isn’t seized or broken)
i assumed it was the door lock actuator as all of the other door locks were working with the switch and fab.
I just replaced the door lock actuator and nothing!
no power or movement at the actuator
what else can it be if only the one door lock is not working?

The relay that clicks to send power is likely to blame, and for the life of me I can't remember where it is.

There is no relay, the door locks are multiplex controlled (i.e., via the multiplex control unit, that is part of the under-dash fuse/relay box).

The cause may possibly be due to an open (break) in the wires. Gently pull back the rubber grommet boot at the B-Pillar. The Yellow (terminal no. 8) wire and Yel/Blk wire (terminal no. 7) are for the left rear door lock motor.
