Hi first post so forgive me if its in the wrong place, I noticed yesterday that my air con was blowing cold on a 20 mile journey, I stopped at a garage and when i went to carry on it was just blowing warm air (Like on a car with no a/c). I tried switching it to manual, Then Auto, Put it on LO then 16c still blowing warm. Stopped again for 30 mins then drove back and it was fine all the way. Today it done the same thing but without the stop starts ie.. Constant journey first 10 mins warm then cold air kicked in. My mates an ac enginer he looked under the bonnet and touched a pipe that was freezing and said that its not the gas or compressor???? any ideas.
