1996 Buick Park Avenue Part Name Needed

#1

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.)


#2

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


#3

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.


#4

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.


#5

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?


#6

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.

I found what looks like the part and purchased it.

I Think this should work. I’ll try installing it tomorrow.
Thanks for figuring this out.
