Connect the ground wire from the fan to the green or bare copper wire from the light switch. ### Testing Once the wiring is complete, turn on the power to the circuit and test the fan. The fan should turn on when you turn on the light switch. ### Troubleshooting If the fan does not turn on, there may be a problem with the wiring. Check the connections to make sure they are secure. You may also need to replace the fan or the light switch. ### Conclusion Wiring a bathroom fan to an existing light switch is a relatively simple project that can improve ventilation and reduce moisture in the bathroom.
