  • Aircon not cold

    My aircon wasn't working when I bought the truck and when the weather started warming up I decided to have a go at getting it working. So I took it to the garage where they tested the system for leaks etc. and re-gassed it. Unfortunately it still didn't work because there was no power to the magnetic clutch on the compressor. The guy ran 12v to the compressor and it spun up nicely so I know that works so I took it home to track down the electrical fault. I found that there was a relay missing (someone had wired a manual switch for the electric aircon fan into where it goes so I took the wiring out and put a relay in) and eventually found the 10a fuse behind the glove box had blown. Success! It was now blowing nice and cold
    Then the weather cooled down so I didn't use it again until yesterday when I found it wasn't blowing cold again.
    The compressor is still turning, the light is steady green, just no coldness.
    Before I go back to the garage, is there anything else I can check?

    If everything seems to be working correctly, then it sounds like it needs re-gassing.

      There's a Groupon deal with ATS running at the moment, £28.95 for regassing - https://www.groupon.co.uk/deals/ats-...ircon-recharge

        when you say the comp
        is turning it turns all the time
        but for the air con to work
        the clutch has to engage
        and if no gas it wont
        easy way to check clutch
        start engine on tickover put aircon on
        if clutch working the engine will rev up a bit
        the old git

          Thanks Growler & Galooph. When they regassed it a couple of weeks ago they said there were no leaks so I'm inclined to take it back there if it has leaked out.

          Thanks Bryan, I meant the clutch was engaged as it should be in order to work.
