A/C Compressor control valve/ scroll valve
Hi folks,, I'm having A/C issue, as my car were stored for about 4 years. I've checked almost everything and all seem to be ok. The low pressure when a/c on is about 100psi. So, I guessed I will give changing that valve a try. It's screwed into the compressor itself. Has anyone replaced that thing? Will Nissan dealer carry it? If so any part NO!! I'll be taking it out tomorrow after evacuating the system. I'll post a pic of how I believe it looks like I found it online. Thanks in advance

FIXED. I have replaced it and A/c worked ice cold. dealer and many mechs told me you need a new compressor
. I found this valve in a shop imported it from China, dealer dose not carry or sell it. Symptoms were warm air / low pressure about 100psi. Not sure but I was told this part fails when A/C turned on at high speed, in my case my car was stored for long time. The one with black o-rings is the original and the chinese one has green rings. I'm gonna clean the original one and then put in ultrasonic cleaner it might work again. Cheers guys
