Hi team. Hope everyone is bearing up.
Just noticed recently with this hot spell that the aircon is not working. Here is my troubleshooting tick list.
Both fans start up as normal but stay on and only stop when the aircon is switched off. The clutch on the compressor is definitely engaging/disengaging when switched on and off. I can hear the click and load on the engine at idle and the revs drop slightly so that suggests it is working. Not surprisingly, the low pressure and high pressure pipework remains at ambientish temp. I have checked the radiator/condenser. No sign of obvious damage but I don't think that means much. Could be a hidden leak anywhere on the loop.
I had a re gas last year (May) carried out at ATS Euromaster. The aircon has been run routinely since then. The technician reckoned the pressure was just below normal before he drained and refilled but that was a year ago. It could have sprung a leak since then. I obviously need to get the car pressure checked as soon as poss but in the meantime, are there any additional obvious DIY checks that I can do myself.
PS - I know the relay switch can be an issue but since the clutch and fans are operating it seems unlikely unless I have overlooked something technical.
