RAGE!!!
As some of you may recall, I was whining late last year about lower than desired AC output, but due to the inexplicable CP events that I have seen during the last 5 years of owning the vehicle, I was distracted, and didn't for a second expect a problem, so no diagnostics took place.
(see previous discussion - Component Protection - Potential Controller Software\Firmware issue )
Now that we are finally getting some warmth in my neck of the woods, it's evident that there's a more substantial issue with the system.
Bottom line is, my AC compressor doesn't kick in.

Idling, AC on - Rad fan not ramping up, compressor not turning on, AC output not cold.... controller thinks all is good... no faults, no codes, no cooling!
Same conditions as above, but AC off - not changes in pressure or fan speed, etc.
I'm not liking this IDE01471 value, but I have to try to figure out what sensor is providing it....
I have also physically checked with my hand on the compressor when the AC button is cycled on and off that it doesn't engage.
Right now, my speculation is that the N280 valve in the compressor is stuck.... this is based on the compressor not kicking in, the pressure not dropping, the evaporator temp not changing, and obviously the AC output not being any colder than ambient temps.
Output test was ran and passed on the rad coolant fan, so that's not an issue.
Output test of the compressor activation was refused by the controller.
I'm done poking around this for tonight, so if anyone wants to throw out some ideas, I'm eager to read them.

IDE01473-ENG98502 Refrigerant pressure sensor: status-Data OKI have also physically checked with my hand on the compressor when the AC button is cycled on and off that it doesn't engage.
Right now, my speculation is that the N280 valve in the compressor is stuck.... this is based on the compressor not kicking in, the pressure not dropping, the evaporator temp not changing, and obviously the AC output not being any colder than ambient temps.
Output test was ran and passed on the rad coolant fan, so that's not an issue.
Output test of the compressor activation was refused by the controller.
I'm done poking around this for tonight, so if anyone wants to throw out some ideas, I'm eager to read them.
