do you have a multi meter on hand ?
at this connector at the drivers winder switch does the orange show 12 volts ? is the black a good ground ?
2 things we have going on here
1st off the drivers door switch assembly when replaced MUST be programmed with a scan tool with programming for it to work as it is a module
i am concerned the old switch was bad and then you installed the new switch and i am assuming it was not programmed is why the new switch is not working
if the orange has 12 volts and the black is a good ground and it has a new drivers side motor in it the drivers switch needs to be programmed and that might correct this problem just with the programming installed in it
2nd thing is if it will not work even after programming the new switch with a new motor and the wiring in the door looking good from the switch to the motor then usually these issues come down to the black not being a good ground or one if the wires in the door jam pass through is broken or cut or cracked
no the diagram says drivers door module which is the drivers switch assembly
and 2 of the wires in that diagram say left front up and left front down
ok we need to see if that orange is 12 volts and if the black is a good ground
you can for testing purposes take a wire and ground it to good clean metal and stick it into the back of the black wire terminal with the switch connected and see if it works with a new good ground

it may be..hard to say right now
lets go after the LF window not working first
ok so pull up the passenger rear switch back probing the terminals in the connectors with the switch still connected switch multi meter set to DC volts one meter lead into the brown wire terminal in the connector and other meter lead to the dark blue wire terminal with the key ON and pushing the switch up and then down will it show + 12 volts one way and -12 volts the other way ?
the orange wire at the switch shows NO volts ? if not see that orange wire is broken in the door jam opening
how are you making out ?
