I have a 2009 Kia Rio My air doesn't work at all. When you turn om the air it
blows hot. I put 2 cans of refrigerant in it last year & it doesn't work. I put 1 can
of refrigerant in it again last week and it still doesn't blow cold. Its to hot to ride
with any air especially when temp fills like its 100.
You must have a pretty good leak,have the system charged and location dye injected into system.
