The ac comes on first thing when you start the car then after 15 to 20 minutes on 2011 Kia Sportage

the compressor will go off and start blowing warm air then after a while it will kick back on and so on , the low and high pressure are good and I replaced the inline compressor switch , I was told their was a temp sensor by the evaporator could that be the problem ?
