LGiles Posted October 29, 2021 Share Posted October 29, 2021 My air con has started making a hissing noise which is intermittent. The ford dealer has informed me this is normal. Anyone else had something similar? Quote Link to comment Share on other sites More sharing options...
anon Posted October 29, 2021 Share Posted October 29, 2021 Usually a sign of being low on refrigerant. How old is the car? Quote Link to comment Share on other sites More sharing options...
LGiles Posted October 29, 2021 Author Share Posted October 29, 2021 It's 2018 which I bought in April 2021. Not long after we realised that the air con wasn't cooling. It went back for re-gassing and all seemed ok and then it stopped cooling. again. In September it was fitted with a new compressor and now an intermittent hissing noise has started. It's at the dealers now and they have called to say that this is normal but seems strange to me. My previous 2014 fiesta never had this noise.

anon Posted October 29, 2021 Share Posted October 29, 2021 It is not normal. The system still has a leak and the dealer is trying to fob you off. Quote Link to comment Share on other sites More sharing options...
Matt Alsop Posted October 29, 2021 Share Posted October 29, 2021 Not normal. It means the system is low on refrigerant. A re-gas won't help as the leak needs to be found and repaired first. Quote Link to comment Share on other sites More sharing options...
anon Posted October 29, 2021 Share Posted October 29, 2021 The dealership is legally obliged not to regas a leaky system. It appears that they have done this twice and have not yet found the leak. I think I would be insisting upon the attendance of an air conditioning engineer to fault find it. (Most dealerships have one on standby when they get out of their depth as it is a practitioner's art sometimes.) Make mention of their legal responsibility if you have to but it isn't right and will keep costing you time and irritation until it is.
