    Hello all,

    I had my aircon regassed on a 1997 Audi A4 1.9TDI by kwik fit around 4 days ago. After that the aircon worked like a charm.

    The problem developed yesterday, when i switched it on the cold air was only coming out of the center left vent in the dashboard, the other 2 centre vents were cold but not as they should be. The vent on the passenger side and on the drivers side were throwing out warm air when they shouldnt have been. Today when i switched it on all three center cents were also throwing out warm air.

    I then opened the bonnet and felt the aircon pipe going into the cars interior near te battery and it had ice build up on it which indicates that the aircon is working fine. The engine also goes under load when i switch the compressor on.

    Ice on the aircon pipes to me suggests that air con is fine, blower motor blows air in like crazy when switched to full, but if thats the case then can anyone tell me y am i not etting cold air inside the car????????


    Just to let you guys know that after switching the engine off you can hear a hissing noise for around 10 secs.

    Hi,
    I recently had my air con re-gassed and the mechanic told me that the actual fan for the air con (seperate from the main engine cooling fan) was not working which meant that the air con would work for a small amount of time, but pressure would build up and up until gas would start leaking IF you didn't get this fan working - presumably to keep the compressor cool (like a fridge/freezer, it works by taking heat away)

    Suffice to say when I get paid my next job is to take mine somewhere they can fix this fan. I've been told its a £150 job plus labour.

    Hope this helps

    The extra fan on the radiator is for cooling the aircon condenser. This condenses the hot gas from the compressor into a liquid by removing heat from it.

    If the fan doesn't run, the gas will get hotter and hotter, making the pressure rise, until it trips the high pressure switch, stopping the compressor. This should happen before it causes a leak, but it's not good for the system.

    Sounds more an issue with one of the heater actuator motors..
    Run a scan
