Need Help on Door Module/Lock

Working on a 2003
Passenger side door lock wont function with either button or
key fob.. Everything else works fine..
So I replaced the lock actuator/latch assembly.
Still NOT Working..

Do you think it's the module ??? Part # is 09389699 which is discontinued. Have to buy both left and right to match from GM which
is over $1200
Any suggestion welcome

The module does "click" when using the lock buttons.. just doesn't activate the actuator

If the door would unlock it meant the lock actuator motor was good.

It is most likely the lock relay in the RDCM. Cheap to fix DIY or by a vendor.

I have a link on that at home.

Thanks for the help guys
Door would not lock or unlock and everything else worked fine, so assumed
was actuator.
