Is this the a/c high pressure switch?
Is it supposed to be capped like that if you only have one fan?
I have this blue and brown plug I'm trying to find out what it plugs into.

That looks like a fitting for a/c. But for the filling of R134a. I cant remember where the high pressure switch is on my car for sure. I'll look in the morning and get back to ya if no one else has.

That is your high pressure line. It should be capped if you only have one fan.

I think your high pressure switch is that thing with two two wires going to it on the very back of the receiver-dryer silver canister from this angle

Re: Is this the a/c high pressure switch?
The high pressure switch is located on the compressor. (to shut down when pressure gets to high)
There is sometimes a switch on the high pressure line, but that is to turn on the sec. fan when the A/C comes on.
The switch on the dryer closes the clutch when A/C is engaged.
