WTB: A/C pressure switch

Brian · #1 06-05-2015, 09:39 AM

I'm looking for an A/C pressure switch. It's on the right (passenger) side of the engine compartment, right next to the radiator and condenser. It's connected to a block-shaped juncture on the metal A/C line running from the top of the receiver-drier to the bottom of the condenser. It's not shown on the diagram I looked up on the current version of SubaruParts.com. It did show up on the dealer's part department's system, but without it's own part number, just a "reference number".

Here is a low-res diagram with the Trinary Pressure Switch colored yellow and circled in red.

This switch is only available attached to the pipe, as part of an assembly.

Yeah. Actually I already knew that was the case from Subaru itself, but If someone is selling from a parts car or random parts they've collected, they could potentially sell it separately.

I have one but there is no way to separate the switch other than cutting the pipe somewhere. The rubber pipe is damaged on it.

I think you might have the wrong switch in mind.

There are no rubber pipes connected to the switch I'm looking for, just metal (aluminum) pipes. If you check out the diagram I linked to above, you may be able to tell if we're talking about the same thing. At the point where the switch connects to the metal block-shaped juncture of pipes there's a bolt type of ring that looks like it would accept a wrench. Looking straight down at it, there's an electrical connector facing up.

I found what you're looking for. I'll see if I can get it apart undamaged and I'll let you know.

Thanks, Blacky!

I appreciate it, but I'm already waiting for one to arrive that another member has sent. If I run into a problem with that one, I'll let you know. I wouldn't bother trying to separate it now. I do anticipate one possible problem: I don't know what kind/size of O-ring gasket I'll need for where the switch connects to the pipe juncture, or if and where I can get a suitable substitute.
