To be honest I am not very sure about the problem.
I faced the same problem with my car twice. once I felt that if AC blower is is throwing less air. After a couple of days my car also refused to start. On checking battery I came to know it had no water. I had to change my battery. Adding a new battery solved my problem.
In another case one of the tankas of the circuit which takes power to AC blower was some how melted. I got that Tanka repaired from an AC shop for almost 150Rs. As Cuore has relatively better quality than Mehan so ideally your tanks should not have any problem.
I suggest that if your AC is cooling properly then you should not take your car to any mechanic as they will solve one problem and introduce a new one in your car.
