Power door lock mechanism on both driver and passenger side locks won’t work on both passenger side doors, front and rear!!! Any ideas where to start all fuses good

I just bought the car so I am unsure I would assume both passenger doors stopped working from the power lock mechanism on any of the cars doors at the same time. I am unsure if this is unrelated but also from drivers master window switch, I can only put down the power windows on both passenger doors if I want to put them up I hafta physically so it from individual door switches.
