Hello, i have a 2020 corolla se. 3 passenger windows wont work from the driver switch but each and every window will work on their own respective switch. Just cant control all the windows from the driver seat if that makes sense. I was thinking a relay somewhere.....anyone know about this or where i can find a wiring diagram? Thanks

Do the LED lights on the Driver's side switches work?
Check the fuse labeled ECU-B No. 2, It powers the multiplex network master switch assembly which is basically the switch group in the driver's door. This fuse is in the Driver's side side kick panel just left of your left foot dead pedal. Hopefully that is your issue, and not the networking that connects all the doors together.
If that fuse is good, maybe the connector for that switch assembly isn't plugged in fully.
