Why don’t my 2000 Ford Focus radiator fans work? I’ve replaced the relay, replaced the fuses, and replaced the thermostat, but nothing changed. Fans still don’t kick on.
Answer: Turn the engine on and the a/c this will send a signal to turn the fan on. Carefully without putting your hands or any thing else in the fan, tap or give a sharp blow to the cooling fan motor. If it starts to run the fan motor is bad replace the cooling fan assembly.
