Default 2388 Air Conditioning Issues

Our 2005, 2388 has issues with the air conditioning system. It seems whenever it is a nice warm day and you want the air conditioning to work, it doesn't. The valve under the buddy seat turns to shut the heat off but we seem to continue getting heat. The windows will fog up. To fix the problem short term, we put a manual valve in the heating line to shut off the hot water. The air conditioning will work then. Has anybody else had this issue? Any Suggestions?

Up next to your AC Control there is a small screen does it flash 02 when your AC quit,s my 2003 2388 did that I was told it was the high pressure cut out. I got a new one put it on and things worked after that. I only had the combine for about a year after that fix can't say if it is still working.

Hi
Have had to replace a few water valves on the combines and cotton pickers.
It just doesn't shut off all the way.

The little screen next to the knobs does not flash any codes. How many of the valves are there on a 2388 that we can change?

My heater control valve leaks so I shut of the valve on the motor where the heater hoses
come out. I turn it back on when it gets cold out.

The Air conditioner of our 2388 just cut out. Thought it was gas. Found that the compressor is not Kicking in. Fuses are all Ok. Power gets to the relay. Relay does not get signal from control unit. Have replaced control unit with other combine. Still not working. Can anyone give me help on this. What else can I check ?

Have you put a set of gauges on the system? It sounds to me like you may be low on freon, and the low pressure switch is keeping the compressor from running.
