Hello all. I am trying to troubleshoot why some outlets inside and outside my house are not functioning, as well as a light switch. Two of the outlets are upstairs in two different washrooms; however, the light switch for the washroom works fine. All the other outlets upstairs are also working fine. I tested the wires connected to the outlets and they have no power. Then one outlet that's located on the outside of the house is also not working, as well as a light switch for an outdoor light that's close to the outside outlet is also not working. The outdoor outlet I'm not sure if there is power to the wire, but for the light switch there is no power. I tested all the breakers for power and they are all showing 120v. I am not really sure where to go next and would really appreciate any guidance. Thank you in advance.
