Mondeo Mk4 Air Con Hissing

[makepeace1]

Hi

I had my car re-gassed a couple of months a go my car then had to go to ford because of a problem with the BCM and they had the car for 2 weeks since i have had the car back the aircon seems to be hissing and is not getting cold

I have seen online that people have had the same sort of problem and they have just been and got the car regassed and it has sorted it but before i do that i thought i would ask for some advice

When i turn just the fans on in the car it doesnt make the hissing / whistleing noise

When i press the A/C button it starts making the noise and doesnt get cold at all even when its set to as low as it can be

When it was regassed they did the pressure test and they said it passed that

Any advice would be apriciated

Does sound like you got a leak somewhere,hopefully when they regassed it they should have injected some dye in so take it back and get them to check it with ultraviolet light
