Ugh, just when I THINK I know everything in my car's engine bay (83 GSL), I come across this little plug thing. What is it? Where does it lead?

THanks AGAIN

 

Wow, never seen that before.

 

Looks like an A/C pressure switch. That is an A/C line, right?

 

Uh oh, lol.

It goes to the radiator, it seems, if that helps anyone. It's right below where the AC hoses used to be, on the passenger side. I noticed it taking my fender off.

 

If it helps, here's a farther out shot.

 

i have the plug that goes there. it ran in between the wires that are beside it (as in instead of those wires hooked up the way they are now, they were hooked into the switch). I took it out when i removed the AC

 

i think it switchs on your time circuits

 

So it's AC related? In that case, it's OUTTA there.

 

Yep,its an AC sensor.If the AC system loses pressure,it keeps the AC clutch from engaging and running the system when dry.

 

Just curious (or stupid) . . . . why does it go go the radiator?

 

It goes in front of the radiator to its own cooler.

 

The A/C Condenser as it were...

DO NOT Open those lines unless you know the system is empty.

Refrigerant has the following bad properties:
1.) Depletes the Ozone layer... While, not a direct harm, still not cool IMHO.
2.) Evaporates at about -40deg F... Good for frostbite. Ask me how I know.
3.) When exposed to open flame or when it has decomposed naturally, turns to phosgene, a chemical agent used in WWI and WWII... Highly toxic.

I reccomend going to the local shop and asking them to drain the system. They'll probably do it for free, or might even give you a little cash. R-12 goes for a few bucks a pound, and there's like a pound and a half to two pounds in a standard automotive system.
