I have a 2014 Silverado 5.3 my ac works great when it’s not really hot or early in the am. But later in the day it has problems when the cooling fan kicks in high speed my ac compressor clutch disengages. And when it kicks but down in speed ac clutch will engage again it will continue to does this up and down routine. What is the problem ?????? Freon is good no leaks works great other then when it’s above about 86 degrees outside. Also the truck is not over heating havnt seen it over 210
