Nissan Sunny 2010 Peace be upon you.. May those who have faced the same problem as me provide the solution. I have a problem with the air conditioner. I checked the compressor and it was fine. The problem is that when the compressor disengages, it blows hot air. I cleaned the evaporator and the problem persists. A while ago, they said the freon was low, so I refilled it, and the problem persists. Is the problem with the evaporator? Does the thermostat in the evaporator play a role? Does the cooling valve play a role in my situation? Whoever has faced the same problem and solved it, please let me know.
