air con stopped working ?

the aircon / climate control has suddenly just stopped working on my 2005 honda crv ! i dont hear the fan or the clunk when the pump engages and its blowing no cold air out . The aircon worked fine up until a week ago ! ive heard no bangs or noises , it just stopped working . Not that i need the aircon this time of year , but i just hate things not working !! p.s forgot to mention , the light still lights up on the switch !
