    Default Mehran A/C Problem Solved

    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.

    the valve are of two qualities. 1.. is of Denso that come with price tag of 1800/ 2.. is of China with price tag of 1000/. Its your choice. No kabli valve can fit in Mehran unit. But original can be diffentiate easily with China one as it has a pathetic finishing.

    Because the pipe that has to drop the water OUT of the car, isn't connected anymore and is having fun in the passenger side.

    There is a pipe that connects to the evap box under the dash, and goes out from the hole in the body (the firewall) check that pipe!
