Having AC problems. When car is first started, the AC will only blow warm (AC compressor does not come on). I have to drive the car several miles, stop and turn it off. After several minutes I start it again and rev the engine up and down for 10 or 15 minutes. Eventually the compressor kicks on and the AC blows ice cold. I can stop the car for about an hour and when I start it again it still works. Any longer than that and I have to start the process all over again. When AC is working I can check the refrigerant charge and it’s perfect. Any help with this problem would really be appreciated. THANK YOU!!
My best guess would be the Air Conditioning Relay sticking or a failed low pressure switch(compressor cycling switch).
