Radiator fan does not come on. Only comes on with coolant temperature sensor unplugged. Replaced sensor and thermostat. Fan still will not come on. Freon is also empty. Could this cause the fan not to come on?

Hi,

If the Freon is empty, the condenser fan won't turn on with the AC system. Is that what you are referring to? Is the engine overheating?

Let me know as much as you can as far as what is happening. Also, take a look at this link, you may find it of interest:.

Let me know.

Take care,
