I have a bathroom exhaust fan with a light and heater function. The Heater has a red and white wire and the fan and lights have a black, a blue and two whites. There is a three switch outlet on the wall in the bathroom controlling these functions. In the attic there are 3 different wires going to the exhaust fan that I can't find out how to connect. There are 3 blacks, 3 whites and 3 grounds. How should I hook the switch to the exhaust fan wires? Please help
Blue, black, and red are all hot wires. Just attach each hot wire and its corresponding white wire to each switches black hot wire and white wire. When finished each switch will turn on the heater, light, or fan.
