Sounds like it could be a short in the wiring or more likely the cooling fan senser has failed, if your car has a separate cooling fan sensor switch or does the ecu control it?

If you got you air vents position facing on the screen the aircon comes on straight away so fan will be in.

+1. If the fan setting inside is set to windscreen then the air con will also turn on.
