sorry to hijack... mine had the same problem... initially the driver ac is warm & passanger is cool but now they r both warm - not cold at all. had it regassed & replaced the front filter near the radiator 5mths ago. btw is making a whining noise when I turn on the ac. it grts louder as I press on my accelerator. any help would be appreciated also any highly recommendations for ac service/fix in sydney area & how much approximately? Thx guys
