How do folks
Is there a diagnostic for checking the air con system?
I recently got a 2006 ESI and when the air con is on, it belts out hot heat even when its cold!

Is there anyway of checking the gas level myself? Took it to kwik fit and they said that theres plently of gas, im not so sure though.
Dealer wasnt much use either, wanted 80 quid to investigate and not to fix it!
Any help would be great
Cheers
