Probably a bad wire between the switch and the PDC or in the PDC.
Low beam battery feed comes out of the multi-function switch on the violet wire with a white stripe. From there it runs to the power distribution center. Inside it goes through a jumper and splits to feed both low beam lamps. As both low beam lights are out the issue has to be in that part of the circuit.
So get a simple test light and with the headlights on and on low beam see if you have battery voltage at the violet/white wire at the switches output.
Then find that same wire at pin 6 on the PDC. Do you have power on that end as well?
Now you need to go to either headlight and find that same violet/white wire. Run a quick test of the lights by running a jumper wire from battery positive to the violet/white wire post on the bulb, if both low beams come on you have a choice,
Replace the PDC costly or simply run a jumper wire from the output of the dimmer switch violet/white wire to the same color at the light side of the PDC.
