Look in your breaker box, find the breaker for the fixture and turn it off. Many times your able to remove the cover on the bottom of the fan/light which in turn allows access to the wiring for the lights/fan and the switch's that controls them. This is done by a single nut or a few small screws on the sides. Sometime you may need to remove the light assembly to gain access. ( You shouldn't have to disconnect the entire light assembly wiring; maybe just 1 wire)
Once you have done this you will be able to see the switch that controls the fan and a separate on that controls the lights.
Remove the corresponding switch by unscrewing the little thin washer looking nut on the neck of the switch remembering which wire connects to which wire.
Take it to the hardware store and match it up with another switch. Ask for help to assure you get the correct switch. You may want to have the brand/model of fixture the switch is from.
Reassemble in reverse order making sure the wire nuts are all tight. Turn breaker back on and you should be good.
