Was the negative battery ground cable ever changed?
Negative. These codes were also not here 1k miles ago when I changed the oil. I always scan for codes, and reset service interval properly.Was the negative battery ground cable ever changed?
Yes, I reset the codes and I have not seen them return. I also haven't spotted a leak anywhere.Have you tried resetting all of the codes and se if they all return?

2013 Cruze A/C off due to high engine temp
The Radiator fan don't work until high pressure gets high enough on the ac. Same manner as it works when your coolant temp gets high enough. Basically only when your sitting at idle. Fan not needed when driving down the road.
Compressor running and high pressure is only 87 - 97. That's your answer right there. You're almost out of freon. High pressure should be around the 250 mark. The reason it's bouncing around is because the low pressure switch is cycling the compressor. Low pressure too low. That be my guess anyways but I'm not there to see what you got going on.
I would slap on some gauges to verify though. Make sure the sensor to the computer is reading accurate.
An accurate diagnosis of the system requires knowing what both the low AND the high are doing. Harbor Freight sells a good gauge kit for $60. I bought my last set on the july 4th sale 25% off. There are adaptors fair cheap at any store that sells freon in those cans. I buy the 30 lb. cylinders. 75% cheaper then buying enough cans to equal 1 cylinder. But I have a NAPA connection.
Since you have a high pressure gauge with your ethos. A kit of gauge and can will work for the low side,.
You'll have to let me know the price of ethos at christmas time this year. I"d like to have a more comprehensive software package over the usual basic stuff commonly available.
I bought toad. It's cheap. And a few happy campers on youtube but I"m not seeing it with the software. See what happens when the obd2 connector arrives. But I have a feeling it was a waste of $130.
That's odd. Have you turned on the AC since?Yes, I reset the codes and I have not seen them return. I also haven't spotted a leak anywhere.

Seems like your narrowing it down to low "Freon"Yeah, the AC off due to engine temp never showed it's face.. It wasn't in the history codes either.
Yes, I have turned the AC on since. The compressor kicks on, the air is running but it's hot and not getting any cooler. Everything cycles and seems to be working. The PCM is also showing it's requested and enabled.. but no error codes are back yet.
Keep in mind the compressor is a variable displacement type. How much it can "throttle back", I don't know.Any idea if the compressor control valve can stop the AC from working, even if the clutch is turning? Seems like this would cause damage to the compressor since it would be running dry/choked off.
If you find your gauges or buy some gauges. A full charged system will sit at around 110 on both hi and low when it's sitting.Yes, I reset the codes and I have not seen them return. I also haven't spotted a leak anywhere.
Yeah, I have been looking in my garage for my AC gauges but haven't used them in so long and cannot remember if I loaned them out or something... my Z28 doesn't have air and I am used to it that way.. so I suppose I will have to buy a new set of gauges to really continue diagnosis. Going to lift it up and look for leaks again and verify the AC High Pressure sensor is working correctly with the AllData manual I just downloaded.

/edit - Oh and if you PM me I will tell you what the price was during the promotion. I can put you in touch with my vendor if you wish.
