ML320 power window problem

I have a 98 ML320 with window issues - driver's side window stopped working recently- no motor sound at all. I have had to replace the switch once before, so I bought another switch and hooked it up with no result. I then purchased a new motor (regulator was replaced about a year ago), hooked it up today and still have no action. Tried switching fuses without luck either. I am thinking it is a wiring issue, but not sure what else would make this happen. Does anyone have any suggestions on where to go next? Thanks.

Possibly a wiring issue, if you have checked everything else.

Usual failure location is in the 'concertina' loom that is flexed when the door is opened, as this takes stress over the years. This loom contains the wiring from the door switches on the console to the motor.

Look for a chafed/broken wire.
