Hi everyone,
I have been having issues with aricon lately not cooling when on. So I took it to local garage (Kwik-fit) for a test. They tested the sysem and discovered no leaks thus proceeded with gas recharge after which nothing chnaged and still no real cooling with aircon on. I was told it must be an internal system issue which they didn't have the quipment to diagnose.
So with new gas and no leaks, what else could be causing an issue?
Thanks
Are the fans under bonnet working when aircon is switched on ( both of the large radiator fans under bonnet should rotate, they hard to miss as are pretty noisy ). Next check is the compressor clutch operating ( you will need a torch even in daylight to check ) with bonnet open and engine running and aircon on, with coldest selected, you will need to find auxiliary drive belt pulleys ( the pulleys are all on drivers side of engine unless your car is LHD ) the highest pulley nearest front of car is alternator, there is another pulley below it, and you need to shine a torch way down to 3rd pulley to see if the centre of pulley is rotating - the outside of this pulley rotates all the time, the centre of pulley is attached to compressor and only rotates when clutch magnetic solenoid coil is energised. If the fans do not rotate could be relay broken or stuck or a blown fuse, if the compressor drive not rotating could be a relay ( fan and compressor relays are separate ) a fuse or the solenoid clutch coil failed. Plenty of recent threads on here about aircon problems, it seems to be one of the main sources of strife on a Jazz, but 99% of the time it is low gas..... rarely it is a stuck relay or blown fuse, never seen anyone on here have the clutch solenoid coil fail.
Be careful around the drive belt and pulleys, look but don't touch - that belt will have your fingers or hand off before you can say 'ouch'..... good luck
