air con/radiator fan
 

Hi i am new to this forum and was looking for some help.My air con on my 03 fiesta is cooling okay as there was a new compressor fitted 2 years ago.The problem is my radiator fan used to turn slowly when i put my air con on,but now it is switching on and off in 5 second burst thus causing an electrical and mechnaical power drain each time the fan kicks in.can anyone shed some light please? THANKS
