Looking for some advice on my air con. I took it to kwik fit to get it regassed as it was blowing out hot air and they did the whole thing and went to test it and they said its not working the machine didn't say anything untowards and there was no charge as it didn't work. the operator thought it was the condensor as he coudn't hear it come on. where is this condensor and could it be something else as it appears the gasses aren't escaping so pipework ok?? really stumped as never had to deal with this type of thing before. its a 2006 a3 2.0 tfsi quattro if that makes any difference.
