Fan fault from ac pressure?

My electric puller fan constantly runs full power while the engine is on. I have replaced the coolant temp sensor and checked to make sure the fan module was working properly.

I was reading a thread on this issue with a 318, and the guy said he had this issue because of a faulty wire on his AC system; the sensor wire that goes to sensor PN 64539181464.

I have no pressure in my AC system (accident, haven't had it purged/filled). Do I need to have my AC system filled for my electric fan to work properly?
