power window and speaker not working

What is your question?

my drivers side window and drivers side door speaker do not work.i took out the door wiring harness and found one wire broke ,so now my passenger window works fine.but my drivers side will not work and the speaker will not work.do the wires go under the dash or back to the rear of the car .not sure where to look next.there are so many wires.or could it be the master switch?
