Hi..apoligies for the delay..
The mentioned noise..do you know exactly where this seems to occur from on the car.and i asume this just crops up as soon as turn the A/C on?
Does the a/c still blow sufficent cold air?
Hi..Sorry for the delay..
Ok..yes if A/C is currently in use you will hear the fan come on the condenser fan in th same area as the cars radiator..If you switch off the A/C then the fan should stop too..so its normal for that to do that..if the fan is producing a unusal noise say squeeling/rubbing noise then it possible the bearings in the fan motor are at fault or the fan slightly siezed..you can check that by spinning the fan by hand with engine off to ensure its able to spin freely..but as far as you description goes with A/C in use it sounds pretty normal to me..I do hope this helps..if you need add anything else or ask anything further then please do so before you rate..
