Hi, I have a Suzuki swift 2015 sz4. The air con is presenting issues. It’s now been re gassed 3 times. First time it didn’t work and due to time constraints with the garage and me we just left it. I then had another garage have a look. They diagnosed an issue with the pressure switch so I’ve changed that and had it re gassed. This hasn’t made any difference at all. Although it blows cooler than with no air con, it is not anywhere near being icy cool or making it comfortable to drive in for long journeys. Any ideas as I feel like I’m throwing money away at the moment. TIA.
