My a/c dont work continiously on long runs. Its performance decreases with milage runs. Recently I got very disappointed with its performance during Naran tour.. Any ways I did some research and find out the problem.
Problem number one is condenser... Suzuki fit the condenser with very small make of delecate grill. This grill usually become twisted during service water pressure cleaning. I find out the original Denso condenser slightly big from the old one having a wide grill mesh design an very tough indeed in Rs3500/.After installation of that condenser I got the cool air all the way long continiously with in normal car engine temperature
Problem number two is the expension valve... This valve is located inside the car caben with a/c. This valve has to be change after every 20000kms. If its oriface becomes out. It cannot exchange cool air with the blower. So blower throughs only normal air. While the a/c box within the car get too much cold that air condenses on its surface and drop water on your foot pad at passenger seat. During the changing of expension valve i found out frozen ice in it. Thats the reason when u start ur car after a long stay that ice becomes melt and the a/c works fine. While during journey that valve choak again and there is no cool air again.
