Initially Aircond was in good condition. My 5 Years viva have been on the road without any failure of giving me cooling sensation eventhough I nvr give it any service. But, because I want to do major service back in few days, I decided to service my 5 years aircond too. Now there are a few problem arise after the service. Belting give a weird sounds all the way when driving. I've check with the mechanic twice but still unsolve. Aircond on a minute or two Then knock off. When the car stop, the air flow is not cool, and there are somekind of fog at my windows. Mechanic said compressor already kaput. He raised the engine timing. But still not solved. Now I can feel the car like roaring because of the high timing
