#1 · Apr 5, 2015 Hi guys I had to turn my air con on today for the first time in a few months. After running it for a while I noticed the temperature was not very cold and certainly not chilled. When I turn off the air con the temperature stays pretty much the same. I've checked the fuse and it's ok.
