Welcome. First off, the passengers door switch is likely the issue for the passengers side not working from that door. Those are common for failing. As for the rest, I think that you either have a power issue to the drivers door switch or the switch itself is the issue. Do you have a test light and are willing to do some testing?
I cannot at this time because i am at work. I have done other test with another expert and here is what is found;
Drivers window brown wire no voltage and continuity (tone) to chassis ground.
Drivers side yellow wire 14 volts.
Passenger side brown wire 14 volts.
Passenger side yellow wire 14 volts.
Gorund wire between passenger front and slider door is clean with no breaks or corrosion.
I changed the switch on drivers side but still not working.
Passenger side goes down/up very slow and needs assistance to finish.
Both sides have the lock/unlock switches not working on the door panels, but work from remote.
OK, at the drivers switch, use a section of wire to jump the light blue to ground and the white to ground. THis is looking like a ground issue as the door switch only supplies a ground for the locks.
The ground is in the the B pillar. This is the pillar between the drivers and sliding door. #5 is the one.
Ok this is for the locks not the window switch, right?
Issues with both.
Ok just trying to get it straight with which harness to jump the colors that you have stated.
I can do this later today if that wortks or don't work what would be the next step for either one.
IS there water or signs of corrosion in the fuse block underhood?
This could be the Body Control Module.
Ok, I will be back in a couple of hours.
OK Mike, here is where I am thinking. Ground is not the issue, but given the other issues, I am starting to suspect a power issue such as RAP relay and BCM in the right dash.
