Dude, aircon issue can be very headache. My Myvi aircon compressor also mati last few months. Consulted two friends who is mechanic shop owner, both advise me to change full set(the whole system of aircon) due to once compressor mati, there will be some small pieces of metal rejected and it will travel around the whole system which will have high chances of damaging other parts other then the compressor.

End up I change everything for rm2.3k. Pain? Of course laaa but at least I won't have further headache like u now. If u only change the compressor, chances is the whole system is not clean yet and it might even damage ur newly fixed compressor too.

Good luck anyway.
