Hello,
I have an Xt falcon 2010 model that seems to have an air con system that works most days unless they are hot. On those days it doesn't seem to work too well and canned up blowing hot air, hotter than the outside air. Don't know if I am doing anything dufferent. It doesn't matter if I change from auto to semi auto with air con on. Is it a low gas refrigeration thing or something else. Has anyone else had this problem?

check condensor fan works and condensor and radiator are clear - check air intake into heater fan is not blocked including screen above fan behind glovebox -

verify if system is same temp from left and right vents
have system pressures tested (preferably) -

or when system is working correctly check thick pipe to compressor is "Cold" when running -other pipe will be HOT - check if it feels about the same when system plays up - if not cold - have gas checked -

if pipe is cold when playing up - scan HIM module for codes and have a self test run on HIM -

Thanks Ted
