2014 Mitsubishi Outlander Sport. A/C will blow cold then blow warm air

What is your question?

I have a 2014 Mitsubishi Outlander Sport. A/C will blow cold then blow warm air. The a/c light (snowflake) will blink as soon as it starts to blow warm. I can press it and make it stay on, sometimes it turns back cold sometimes it doesn't. I had the compressor checked for a leak and no leak was found. I have replaced the expansion valve and the a/c pressure switch and it still does it

What makes this problem better or worse?

It can happen at anytime
