had a mad panic moment when i realised my aircon wasn't working and with the hot weather seamingly upon us I wanted it to be working. It was just dead, nothing happened when i pressed the button, not even the light on the button worked. So i set about checking the fuse ... turned out it wasn't working because i didn't have the fan on!!! duh. i pressed the button for no reason in the first place, but it didn't work. Never mind!
