Check this out... I have four switchs for my celing fan in my living room 2 on each side of the room 1 3 way and 1 reg switch in each gang box only one side works also light in bathroom do not work only getting 3 volts on the multimeter this bathroom light is also on same circuit please help

Ok, if you have four switches for the ceiling fan, what are they supposed to control? Is it a 3 way set for the motor and a 3 way set for the light?

The 3 ways control the fan and the reg switch turns the light on and off

So you have two, or three switches for the fan motor? And one for the light kit?
