Not a question, but a comment on your recent article about a guy with a GMC Envoy with a/c cycling from normal operation to poor operation with fog coming out the vents and then recovering to normal operation after being shut down for awhile. That sounds exactly like a low refrigerant problem. The evaporator super cools due to very low pressure from a low refrigerant level causing icing on the coils which restricts the air movement. Then after sitting for 15-20 minutes the ice melts and the a/c appears to work normally again. I’ve personally experienced this years ago
