I have just removed the pollen filter which was so filthy and and also had some leaves fall out. I have then put the air con on at full blast to blow any remaining grime etc. I havent put a new filter back on just going to halfords now but its no different in temperature. The car has only done 33k milage. Surely it wont need re-gassing? I bought the car with just 15k on it. Its not had cold air like since bought it. My mate has a zafira and his is sooo cold. Any suggestions?
