I have another question.. What If I dont know which wires go to the light or the fan?? I bought switches online through a mobile home manufacturer and was going to replace them. They were the switches where the wires just lay in the box. Well it was more work than I expected and when I was done the light did not work!! I dont know if I did not put the right wires in the box in the right order.( there are six wires that go into in switch 2 white 2 black and 2 ground) So I decided to just put standard switches in but now I dont know which wires go to what....
I hope I can get this done without calling an electrician...
Did the fan work and not the light? Typically, there would have been a short length of wire connected between the bottom of the two switches that "jumped" the incoming power from one switch to the other. The switches you are replacing used a technology called insulation displacement and at the factory where your home was built the electrical installer used a special tool to push the wire between the terminals. These type of switches are somewhat difficult to replace without that tool but it can be done.
As 300zx said, it would be typical that if you looked in the wall where your wires are you would find two lengths of romex headed up and one down. Each romex is a white jacketed wire containing one each of the white, black and bare ground wires you are describing. The two headed up toward the ceiling are going to the light and the fan and the one down is the incoming power.
You don't sound very comfortable working with this and it might be worth the expense of hiring an electrician. If you replace these switches with the conventional type switches (with screws) and use a box you will have to enlarge the hole in the wall as the size of the self-contained switches you currently have is smaller than the size hole you will need for the box. I am glad to answer your questions but I don't want to take you out of your comfort zone.
