The car stopped blowing cold air?

Well guys, just ignore my previous reply because I just went and checked that compressor again and there aren't two wires running into just behind the idler pulley after all. I would have bet my life 1000X over I felt two wires running into just behind the idler pulley a couple days ago. In any event the compressor I did get in the mail today. The "clutch area" and the idler pulley all turn together at the same time, just like the compressor on the car. That being the case I'm hoping it's just the control valve in the compressor that is the issue.

Thank you. Yes, the clutch is always engaged on both the old compressor and new compressor. Now I did apply 12 volts to the switch on the new clutch and you can hear a click, but there is no movement on the front whatsoever, such as a clutch engaging. As mentioned earlier the operation of the compressor on the same, make and model of car (2015 Genesis Coupe 3.8) that has a working A/C shows the entire front of the compressor turning continuously whether the A/C is on or off. There is no visible cycling of the compressor that is visible. Could this be an internal clutch of some sort? I've checked the clutch via VIN number and the clutch I received is the right clutch. I should also include that with the belt off the idler pulley on the installed compressor turns pretty easily. Doesn't feel like there is any real compression or engagement, whereas on the new one there is noticeable resistance when turning the spindle by hand, but that could be because I have not removed the plastic plugs out that come on the compressor, which may be causing the resistance.

Attached are a couple pics of the new compressor and my turning of the new compressor. Thanks again

Thank you. I have not been able to put any voltage on the original one due to clearance issues. I will have to remove it to check it, but based on how easily the idler pulley of the installed compressor turns I suspect something is wrong with the compressor. It just turns too easily for me to fathom any compression is takin place. Of course, I will not know until I I check it once removed. At this point I would be pleased if it were an issue with the compressor and not the EC!

Thank you for the reply. If I can find a way to get power to the compressor without having to remove it and can hear it click, then I'm going to guess the control valve is the issue. When my friend evacuated the system after having recharged it a week earlier. So, I could remove the compressor, he said the unit was only slightly low on refrigerant and prob not low enough to prevent the compressor from coming on. Also, as previously mentioned, the RPMs of the vehicle did fluctuate when I would turn the A/C on, and even though no cold air came out I would think the compressor was being engaged based on the RPM fluctuating.

I've read most of the issues with this compressor is with the control valve going bad and not the actual failure of the compressor itself.

I will definitely let you know. A friend of mine asked me something about some door wiring harness and I told him to ask you guys because I had no clue what to tell him, and that you guys were the best chance of finding out what is going on without having to go to the dealer for a very expensive repair. If he decides to contact you, I hope everything works out for both of you.

Have a blessed evening.

Good evening,

Well, to follow up I took the compressor out of the car and there was a hole in the top of the compressor and when I turned it upside down to get the oil out all kinds of shiny metal objects fell out things fell out of, lol. I actually think I may have knocked the hole in it myself when I was trying to remove the alternator, but I know I didn't cause any other stuff that fell out. I'm enclosing pictures. I'm now waiting for the receiver and dryer to some in. I know I need to flush the system but am unsure of the way to do that. Any advice on that? Thanks

Sorry, I think I replied to this only my friends account, so I'm going to reply again.
So, I got the compressor off and there was a big hole in the top of it. Turned it upside down and all kinds of metals stuff came out, lol. I'm now waiting for the receiver and dryer to come in. I know I have to flush the system but have never done that. Any advice on the proper way to do it? Thanks

Hi there. I wanted to let you know that the compressor was replaced and now the A/C is working fine. The hole. I'm guessing I put it there when I was knocking the alternator to get it off because it definitely was not there to start with. Might need to replace the alternator soon as some anti-freeze leaked through the connection where the upper radiator hose connects to the motor and soaked the alternator. It almost looked as if the alternator was what was leaking anti freeze. As of now it's still charging based on my readings, but my son had an issue a few nights ago where the engine kind of stuttered and the battery indicator flashed briefly on the instrument panel, and he said the car would not accelerate after that, so he pulled into a gas station parking lot. I got there and couldn't find anything wrong. Since it was at night, and he had the A/C and headlights on something like what happened sounded to me like the alternator wasn't charging properly, but it was when I checked it with the multimeter. Who knows?
Thank you so much for your assistance with this issue, it is greatly appreciated.
