I'm having some problems with this plug, not sure what it does but most of the time when I turn on my ac and the clutch doesn't engage.....I wiggle this connector and it engages and my ac works fine? I'm hoping that someone knows how to get another one of these connectors or has a solution to my problem?? Thanks.

 

It's the high pressure safety cutoff.

Make sure the barrel of the switch isn't expanded, and that the pin of the connector isn't flattened.

 

 

Thanks for the info! Do you know where I can get a new switch?

 

Here is a link to a 1986 high pressure switch.....it doesn't look like mine???

That's it

Held in the compressor body with a snap ring

You probably don't need a new one

 

Well I did quite a bit of searching on the web, and the only thing I can figure is the reman compressor in my 86 must be for another make of vehicle?? I cannot find another style switch like that one from any 82-92 third gen????

 

Sofakingdom.....look closely at my pic....connector looks nothing like the one from partsgeek???

 

I'll try to explain more in detail what is going on.....when I start my car, I turn the AC on, warm air coming out of vents, I open the hood and see that the clutch is not engaged, I turn the connector and the clutch engages. AC will work until I shut car off. After getting back in car, I start it and I usually have a 50% chance that the AC will work or not. If it doesn't, I go out and move the switch and the clutch engages again. Once the clutch engages, moving the switch normally has no effect on anything....it's only when the AC is not working??? Hopefully this makes sense??

 

Not sure what you're asking about; looks IDENTICAL IN EVERY WAY to me. Just like every other one of those I've ever dealt with before; new, old, used, failed, on whatever web site, in whatever car, whatever whatever whatever.

I'll try to explain in more detail too:

Locate the part in the back of your compressor. Observe the snap ring that holds it in. Using a pair of snap ring piers, remove said ring. Pluck the device in question from its hole. Observe (one of my favorite-most concepts.... OBSERVE...) the part you took out. Compare it carefully to the one in the pic. Please report on ANY differences, however trivial, that you might OBSERVE. Feel free to post whatever pics, questions, whatever, you might have. I doubt you'll have any, actually.

But, that's really not necessary. Sounds like (a) your AC system is working fine (might need some Freon, but that's like saying your car is working fine but could use a bit more gasoline) but has this intermittent electrical connection that's designed to protect your system from turning into a bomb in case of blockage or whatever; and (b) the fit of the pin in the connector to the pin in the switch is loose. All in all, not too tough of an obstacle. Nothing but a hill to a stepper. Let alone a climber.

 

Ok. Thanks.
