I think the bearings in my air con radiator fan are defective, because the fan makes a loud whirring noise when the air con is switched on. I've also had a close inspection when the air con is switched on and off and its definitely this fan, which is the bigger of the two.
I don't believe I have the relay fault, as the fan works perfectly fine and continuously, whilst only the air con is on.
Can anyone please tell me what size this fan is, as I want to order one asap. Thanks for any help.
