You might also have a bad switch. Temp sensor should be o.k. if the engine temp. goes and stays at normal and the upper and lower heater hoses are hot.
The fan motor has failed and will need replaced.

Check the fuses, check the relay and then check the fan motor.
bad fan or bad fan relay
Check fuse first. if ok then check you have power to the fan. If not it is probably the thermo switch which switches on when the engine gets hot powering the fan motor. Be careful when checking the connections that the fan doesnt start and injure you
