What dvt873 said….. also. Have you tried washing the radiator out? Sometimes it’s the simple things that get overlooked. I’ve never heard of an a/c shutting down because the fan stays on too long…. Even though it shouldn’t be staying on too long. . 275 constant high pressure at 92 degrees with the fan on all the time is high. It sounds like the high pressure isn’t dropping low enough to let the fan turn off and the longer it runs the higher its gonna get Eventually turning the a/c off from high high pressure. This being a pro star have you actually connected a laptop to it to see why it’s shutting down or is this something someone is guessing at. Can we get pictures of the a/c gauges after the truck has been running long enough for the pressures to level off? Also you need to make sure that this isn’t one of these jobs that someone got pissed off at international and started bypassing switches and shi#t. I’ve seen it over and over. But all we can do is throw suggestions at ya since our hands aren’t on the truck
