I was diagnosing it over the past couple days and now I'm at the end of my knowledge rope.What I've done.1. Checked the main fuses, all the fuses are good, no issues there.2. Checked the in cab fuses, all the fuses are good, no issues there.3. Threw a gauge on the low side and it read fine. I don't have a gauge to read the low and high side. Someone suggested pulling and jumping the pressure switch on the accumulator to see if the compressor would engage, low and behold it does. However, it does not blow cold air. With the clutch engaged and compressor running, AC on max, fan on high, ambient temperature air comes out. I let it run for a bit to see if it would get cold, revved the engine to about 1800 for a few seconds, nothing. Not even a hint of cool air. BUT I know the compressor will engage. However, it will not engage from the normally when the switch is connected to the accumulator. When I did put my cheap gauge on the low side, it did show that the system was on the higher side of normal, but not into a "danger" zone, still green, for whatever that means.  It would probably good a good idea to get a hi/low pressure gauge set just to have. If anyone has any recommendations I'm all ears. It's likely that I'll need to take it to a shop if it needs evacuating, but yeah if I can do it myself that would be awesome. Thanks in advance for your help.</blockquote>
