![0612182012a](https://global.discourse-cdn.com/cartalk/original/2X/9/918208060c3c46cbf7f454e220c14dd069fc6547.jpg) My car released all of it’s refrigerant a few days ago. I Put some spare refrigerant in and tracked the leak back to the small hole in that top left cavity you can see in that picture of my a/c compressor. I feel like that was a high pressure relief or something like that and needs a new cap or something. But I really have no idea, I’m pretty illiterate when it comes to cars. If someone could tell me the name of the part so I could track a new one down I would appreciate it. I haven’t found anything helpful googling around, so I’m at a loss. (I have more refrigerant and a vacuum pump with the needed equipment for evacuating the air when I get to it.) ---

The repair guide shows “system control switch”, there are two. What is on the end of the blue wire in the picture? ---

The blue wire is connected to one of the pipes leading from the compressor and goes back a few inches to another connector closer to the engine. It looks unrelated. ---

I’ll go look for a hanging wire that looks generally the same as the other one that’s connected. I had just assumed that it was missing something to fill the hole rather than an actual connector. ---

I found nothing, I’d assume I could at a minimum find a sheared wire or something. Could you link me that repair guide you spoke of? ---

Some of the older vehicles had an aluminum plug in the unused ports but this one shows a switch. The diagram may be one that covers all applications so it may not be accurate. ![Harrison%20compressor](https://global.discourse-cdn.com/cartalk/original/2X/f/fde7477202f02b4e3cb3ba85d080954a1d13e001.PNG) ---
