I talked to mechinic that I have work on the car . He said that most likely the pressue is too low in the system that is we it cuts out. From what I have been told that is bad idea to by pass the sensor. Not that your idea isn't great idea. I was also told that evapator core is usually what leaks on the system. So I will think I will start my advunture their with the air. For this summer I will just keep adding r-134a to the system. But right now the system blows 62 degree air.
