One question
When the ambient temp is 105 and the engine is fully hot (after long drive but now at idle) , the hi pressures go up above 300 and cause the high pressure switch to cut the compressor off. The refrigerant charts say that at 105 a pressure of 325 is fine but the switch cuts off before 325. So when the weather is the hottest and engine is hot, compressor starts rapid cycling. This seems to be an issue. Experts?
