    Default Air Con Problem?

    Have recently bought a 55 facelift Design with Automatic Air Conditioning.

    The air con does not seem to be getting cold enough.

    Am I correct that I should be able to get icy cold air from the vents with the air temperature set to minimum, and the fan switch set to A. I thought the system would work as hard as possible until the general temperature selected was achieved.

    The system does not cool the car. I have had the system regassed, and the compressor clutch is engaging, all the fuses appear to be fine.

    The only thing I have noticed is that it does not switch a cooling fan on for the radiator, when the A/C is operated, is this normal?

    Any help greatly appreciated.

    Just took the pollen filter out, and the system is closing the flap for recirculate OK when air con is selected.

    If it is set to minimum temp and with the fan to 4 for maximum cooling (according to the manual), the drivers door air vent is cooler than the other three.

    Is there a problem with the heating / cooling flaps behind the dash???

    Anyone seen this before?

    I,m thinking that the system may still be drawing air past the heater matrix, as well as via the air con evaporator.

    Possible??

    What engine does your one have mines a 1.8 VVT and it has the same problem, does yours make a hissing sound when running the air con?
    I thought when running the aircon the cooling fan comes on regardless of engine coolant temprature but this doesnt seem to be the case on the vectra

    It's a 1.9 CDTI 150.

    No it does not make a hissing noise. I asked the question about temperature as I did not know how it should perform, as I had just bought it.

    I have taken it back to the garage that regassed it, and the pressures were down again, indicating it had a leak. I have also noticed that the compessor is now making a rumbling noise, as the refrigerant is low.

    I have had a UV light all over the system, but have only managed to find two tiny spots of dye on the upper connection to the condenser. There was also a small amount of oil present on the union, so I am going to get the seal replaced and the system gassed up again.

    Will update this when the work has been done.

    Vehicle : Vectra c

    Trim : SRI Estate

    Engine : 1.8 VVTI

    Year : 06

    Angry A/C condensor problem !

    I think there is a design fault here. I also have a facelift model ( 06 SRI ) and have had the same trouble.

    Heard hissing noise and had a straight re-gas at Kwik Fit. This was fine for a couple of weeks and then it happened again.

    Took it to my local auto leccy / air con mechanic and he found a leak on the AC condenser. He said it was the second facelift he'd seen this week with the same problem.

    Cost is £423 Vx parts or £325 aftermarket parts.

    How could I go about getting VX to cough up ? Should point out that car is out of warranty ( May ) and that I did the last service myself ( Genuine parts ) as I have been made redundant. A/C has never been serviced until now.
