Hi all the sifus in lyn,

My old faithful a 97 proton iswara is having an issue. When I am stuck in a jam with the air con switch on, the car will ratter violently then engine mati.

Fortunately, i still can start my engine after the engine mati. But when I stuck in a jam without the air con, the car works fine.

However, while driving without traffic jam the air con works fine. Need help on the issue. Thanks in advance.
