Default A/C problem

i have just bought a 2008 H3 and the cooling quits working. When it works it blows extremely cold air & I have had the Freon checked & it is full. When it goes out & starts blowing hot air, the only way to get it going cool again is to disconnect the battery so it resets the computer. Once done & reconnected it blows cold air again. It just keeps going out. Any suggestions?

Was the HVAC wire harness replaced per the recall?

Do a search here for HVAC issues, there is a ton of info.
