Mk5 Fiesta Aircon Not Cold and Clicking from Under the Bonnet

[Skeeter]

Yo

My sisters 07 Fiesta's Aircon has stopped blowing cold (still does hot ok) and when the AC is on there is a 'click' noise from under the bonnet, around the drivers (belts) side of the engine that clicks about once every 10 second. Im thinking its something like something is failing to engage or something, but im not sure. Any ideas on what it could be or where we should look before taking it to the stealers?

Cheers

Wikipedia called it the 5th Generation Fiesta or the Mk6... so I just took a guess... lol.

It would be the 6.5 then, with the 'nipple' headlights.

Would not using the aircon much cause the gas to go low? Aparently this is the first time my sister has used the aircon for ages, and she hardly ever uses it.

Mate of my dads works with aircon systems or something, he was going to regas my old Mondeo before it got totalled, will see if we can get his opinion on it.

Cheers
