The electricity in one of my walls is out. it includes outlets on either side (2 different bedrooms) as well as the lights in one room. The rest of the outlets and lights in the rooms work that aren't in this wall. I've been in the process of changing outlets and switches(in other rooms, but possibly on the same circuit as these rooms), but I'm pretty sure this ONE wall isn't on a different breaker/circuit than the others in the room, so I think my wiring has been done correctly. any way to figure this out or should i call an electrician?
