All four of my windows won't go down after my little girl waste cool aid on the switch, I bought a new one and all it do is buzz when i press it down and it don't light up until I press a button its not working at all I checked the fuses, window motor and regulator, I even put a new motor an regulator in and it still don't work, me and my uncle tested all the wires to with a test light and all of them getting power in and out, not enough power coming out to work the motor, we checked everything. I know without that main switch none of the other windows won't work. I want to ask this do my light switch have anything to do with the door because when I turn the lights on it doesn't do nothing not even buzz, do you think its a short somewhere? I'm stumped on this problem please help me.
