I had just had my A/C system recharged by CCCC, and now it's working fine. This issue had been going on as an ANNUAL problem, and when I took the car to the dealership (apparently THAT was an annual problem, as well), I was sold new parts in addition to a recharge.The mechanic at CCCC was not able to see an obvious site for leakage, but what he did was add a colorant to the freon for a future diagnosis. Wow, what forward-thinking concept. If I do need to have the A/C serviced once again in the future, at least the mechanic will know where and what the problem really is. I think any customer would appreciate that!
