Mine has a similar problem. It's a 2002 LT and every morning when I first start it, the air conditioner makes a clicking sound for about 3 seconds. It used to just do this but now will continue to click for 10-15 minutes after I first start it but not as loud. It will also stop blowing cool air at times (normally when I'm idilling for a while) and sometimes the outside temperature will read 50 degrees when it's 90 outside. When the AC starts cooling again the temperature reads correctly. I think a post some time ago said it may be the "AC accuator cam". Any ideas out there?????
