Thing is that I replaced the Pollen Filter a week before the Heater Matrix got replaced, It was full of crud & dirt and the A/C really was cooling ice cold. However at that time I did not have the heater matrix connected, it was by-passed since originally the previous owner had a leak and simply removed the piping.
The fan did come in but I can assure you that the Car's Temp was not even at 90C so it could be that the AC Rad was warming up. I know that to refit/replace the heater you have to gas out the AC system but only after I did that (or rather the mechanic) he cleaned out the system, vaccumed it, oiled it and even replaced a couple of seals, but after giving it back to me, the car never cooled as before.
Now here in Malta we have high temperatures with high humidity, last year the temp rose to 48C and the A/C was like a charm, if set to LO it would freeze you up. Now I don't know what happened ! Could it be that when they took the condenser apart and gassed it they touched something else ? Its been like thins since the heater replacement. I'm not ready to fork out more money just yet!
You mentionned the AC Filter and valve, could they have gone? Could it be that the mechanic put the wrong gas ? Someone said to chech if the Compressor was kicking in, at the time I was sure but now i am a little bit weary ! How much would the Filter and valve cost?
I'm supposed to see a new A/C guy tomorrow, hope that the gas is the problem ! Any ideas would be much appreciated.
Cheers
I am sorry, I meant the A/C dryer filter. It is the round filter on top of the evap unit that has the trianary switch on it and sight glass.
The expansion valve and A/C dryer filter need to be replaced. call your mechanic and ask him what he put in?
If he did use the wrong gas you need to have him do it all over again and flush all the lines, replace all the o-rings, A/C dryer filter, Expansion valve to make the system right again.
Either that or you have a leak!
Also check the compressor 12V wire, could have come unplugged.
But if system not properly charged the compressor will not come on.
