Made a loudclunking noise when turning a/c on

What is your question?

6 months ago on my 2005 Honda Cr-v this loud clunking noise started when turning on A/C. Felt as if it was going to stall and engine shook. Now it doesn't blow cold air out but the noise has stopped???

What makes this problem better or worse?

Engine is warm

How long has your 2005 Honda CR-V had this problem?

6 months
