They should both run the same way,sucking air in from outside

Changing the polarity over will normally make the fan run in the opposite direction

When you say you changed the wire over,what did you do exactly?
A fan is a dc motor,and they can be changed in the direction they run by reversing the polarity.It is more than possible however,to add a little circuitry to ensure the fan will only run in one direction,hence in my second post i said 'normally' when refering to reversing polarity.If you have just swapped the connectors over on each of the fans,then this wouldn't work,but if you have changed the polarity(= and -) on the one faulty fan,and this still didn't work,then it's not looking good im afraid.It would be messy and difficult to put the fan on the other side of the rad really.Imho you would be better off getting the correct fan,from one of the tvr breakers if you dont want to buy new,and fitting that.

You might not need to go to the trouble of removing the fan.Quite often the connectors can become loose and corroded/dirty,so your stop/start fault when you move the wires could come from this.I would first try reversing the polarity on the n/side fan to try and make the fan run in the correct direction,just connect the two wires the other way around to how the connector will presently allow you to connect them,then you are reversing the polarity.Just do this briefly to see if this changes direction.
If your fan does need replacing,one of the breakers like Bell Hill will have a replacement :-01373 834252

On some fans you can remove the fan blade unit and refit it the other way round. Might be worth a try?
