Exclamation No power to Door locks

Very new here but looking for help.

I have a 2005 3.4 Impala 7th Gen.

Long story short new to me car I'm fixing all the little things, (Window switch, fuses, replace fobs, etc)

My front doors don't lock/unlock, the rear is working fine.

Ordered new actuator opened the door and swapped but still no love.

Put 12v battery to the actuator and it functions(old and New).

I plugged a voltmeter to the door wires no power even when the switch is pressed.

MY Question is where do I start looking?

Short of pulling all the wiring out of the door looking for a short, where should I look?

Does anyone out there know a place to look or a better way to test what my issue is between the actuator plug and the rest of the system?

Also, is it related that just the front two doors are effected?

Any help is greatly appreciated.
Thanks for your time.

I would pull back and open the rubber accordion conduits in the LF (and then RF) door, near the hinges, and examine the wires inside. It is common for the wires to break or partially separate due to bending and wear.
