Any experts in air con out there? I've got a problem not with the scooby but with a ford (I'm also asking on ford forum), just bought CMAX 2L TDCI and the air con didn't feel like it was doing much at all. Now weather really hot (at last) I decided to get a refil bottle, during the refil I could hear the clutch coming in and out and the bottle gauge kept varying in pressure...that night the air con felt like there was a bit of cooling for once and could still hear the clutch. Checked it again on the low pressure pipe in the morning and it had zero pressure, thought that was odd so checking the air con pipework on the scooby and the low pressure pipe has pressure - so does this confirm my ford has a leak? Running the air con following day there's no difference in cooling again from fans on to having ac switch on...bugger.
