Windows wont work on 1999 Ford Mustang

I went to the mall for an hour and i come back and my windows didn't work at all. no sound no nothing. I checked the fuses and they all seem to be good. I bought new motors but i don't know what is wrong.. Any help would be nice

you will need to check if there is power and ground at the master switch.

blue/ black is power

black is ground
