2012 Ford Escape A/C blowing warm
 

Hi. My 2012 Ford Escape blower and A/C went out on me. The blower only worked on 3 & 4, not on 2&3. The A/C started blowing warm. I replaced the blower resistor, the blower came back but the A/C is still blowing warm. I replaced the A/C relay, no change. I measured the refrigerant and it measures as being full. The compressor is turning. If I leave the car long enough, a bit of cool air comes out then it fairly quickly warms up to room temp. Any suggestions?
