Power windows not working

Need some help. My power windows do not work at all. I light tested all fuses and the relay. And even the main switch. Lights up when I push every button except for the passenger window button. Could this somehow cause none of them to work? Also, when I push the driver button with the light tester grounding the switch (think the ground wire is out by the way. I had the light tester stuck in the ground wire in the harness), it makes a buzzing noise. I am at a loss here.

P.S. My mirrors and locks do notwork either. Not sure if that is related.
