My 1980 was purchased new by my uncle, and has been in my possession for just over two years. Car was a base model car, not originally equipped with AC. Uncle paid the dealership to have AC added. Initially I assumed the AC was using all factory components, but I noticed the hose routing differed from the FSM. In the folder of paperwork, there is a warranty card, with the name Southeast Air Control, Inc. Car had 340 miles on it when it was installed.

I'm in the process of determining what if anything is wrong with it. Compressor is not locked up, and I get a light hiss when pressing the schrader valves on both the high and low side.

There is no relay plugged into the factory location, but now I'm not sure if this kit would have used the factory relay location.

@zmanofwashington I know you are the Z Car whisperer, so maybe you have heard of this kit.

The last photo is where that black wire coming from the compressor enters the vehicle.

Turning on the AC should just be move the directional selector all the way to the vent position (I have a label that says "A/C", and you can see "Vent" at night when the dash lights are on).

Company is still in business. Called them, but they have no documentation on their older systems. They told me to just take it to a shop. "The system isn't complicated" was a direct quote.

You didn't say how the system is malfunctioning, but I'd try the simple solution first and charge up the system. Many of them won't kick in when refrigerant is too low.

I don't know the condition of the system. I removed the belt, but don't know if the system uses the factory relay or has a hidden relay somewhere.

I'd need to convert to a newer style relay, since the factory ones are no longer available.

I'll get around to it one day

So evidently you're not trying to make it work at this time? I'm still not clear on what you want to do, other than changing to a newer style relay. Maybe I'm missing something. Seems like it would make sense to put a belt on it and see if it works.

If it's operating properly, you can run the system with the current relay setup and you don't lose anything. Electrical changes such as changing the relays can be done without releasing the refrigerant.

If it's not operating properly, then it would seem to make sense to find out what's not working.
