Check the following items.........
1. Freon levels.
2. Electrical harnesses for the a/c system.
3. Cooling fans.
4. Pressure switches.....
If the compressor will not come on at all, it is not because the system needs charging. Check for a blown fuse, disconnected wire at the compressor, or a defective compressor clutch.
The compressor on my bus failed causing the emergency brakes to come on.
The a/c clutch will not engage and the compressor will not come on.............
Buy a new one stupid.
Not enough information to suggest an answer.
A remanufactured engine for your vehicle would not come with an AC compressor. Your original AC compressor would be reused or replaced with a new or remanufactured compressor if needed.
The cable compressor should come with an instruction manual which you should read before operating the cable compressor. There are also some instructional videos on YouTube.
The compressor is coming on because you have the heater set to defrost. Take it off defrost and the compressor will not come on. I would suspect the compressor is locked up.
Yes your compressor comes when you set your thermostat to "Fan" setting and you have it on cool setting.
Low pressure relay is bad! Check freon pressure, if it falls too low, the compressor will not run (installed for safet of compressor)
