If the system has been left open for an unknown amount of time you need to replace the evaporator and condenser and you likely need all the hoses and mounting brackets.
Eh, maybe true. Condensor yes, Evaporator is an 8 hour :taco: job. You can usually flush them out. I like the flush kit they sell at Advance with the flexible tube.

That's actually a really helpful video. Those multicolor vacuum lines you were holding up are actually the vacuum lines that control the smog devices. Those are irrelevant, you can yank them out. The two electrical plugs you touched were the cannister purge solenoid plug, and the ECU test plug. Both irrelevant, you can yank them out. Right where the evaporator core lines come through the firewall, there should be a hard plastic vacuum line that goes to the HVAC controls. You will probably need to fish another vacuum line through the firewall.

So what were the multi colored lines coming from the back of the controls inside the car? I was under the assumption those control where the air blows.

Correct, there are multi-color vacuum lines under the dash that control where the air comes out. It's a different set of vacuum lines than the ones you held up in the video. I'm going to over explain this for clarity, not to make you feel stupid, or be condescending. Frequently we have people on this forum afraid to ask questions because they are afraid they will expose a lack of knowledge. The vent control switch (the switch that controls where the air goes; windshield, your face, your balls, etc) on your AC control panel is a vacuum switch. On your HVAC box under the dash there are a handful of vacuum solenoids, and the switch directs engine vacuum to these solenoids to open and shut doors inside the HVAC box that determine whether or not you get air on your nuts or not. There could be leaks in that vacuum system anywhere, but the most obvious reason that it's not working is because it has been carb swapped. It's almost a certainty that when the previous owner carb swapped the engine, he neglected to hook up that black vacuum line to the engine. Getting the air to go to different vents is likely an easy fix. You need to run a vacuum line from one of the nipples on the intake to the black line on the back of the vent control switch. Vacuum line is pretty cheap, and you should be able to splice it together with basic vacutite connectors from any parts store.

Getting the AC working might be more complicated. You are going to need to flush the condensor and evaporator. You will need a source of compressed air to do that. Is the factory accessory bracket still on the driver's side of the car? It's a single piece bracket that mounts to the driver's side cylinder head that the AC compressor and power steering pump attach to. You are going to need a new Compressor and lines. The drier cannister also needs to be replaced. If it's still on the firewall, it's been left open for too long, and sucked up too much moisture. Rule of thumb whenever you disconnect an AC line is that you change the drier cannister and orifice tube. There are also electrical control issues that need to be addressed. I know the AC system interfaces with the ECU, and the fan solenoids. You might have to do some custom electric work to get it to work with a carbed engine. It's been done before, but it might take some research. The AC system will need to be charged when it's done. If you haven't done it before, it's better to let a professional do it. The cost of a one time service is about equal to the tools you need to buy to do it.

LOL as my grandfather use to say, I don't know :poo: from shinola when it comes to these things. As we use to say in the Marines, I need it broke down barney style. I ain't afraid to say I don't know. Thats why I'm here asking. I already got about 1,100 into just paying someone to rebuild the front end, redo the plugs/wires, clean up some of the wiring, etc. That's not including what I paid for parts. I wanna be able to at some point be able to do some of this stuff myself. I'm just not naturally mechanically enclined. I appreciate you taking the time to explain this.

I've located all but the last one. 59007. Not seeing a condenser or evaporater. How would my setup for ac be different considering my carb set up?

Every V8 Mustang 1986 and newer is EFI only. For what it's worth, O'Reilly store brand A/C compressors are made by Four Seasons.

Both from Bumper to Bumper

4 seasons condenser 40471
4 seasons evaporator 54557

on the difference between EFI and Carb. I honestly do not know, I believe that these all came EFI in 1995 from the factory.
Yes I know they came efi. But being my car is carbureted. IE, the ECU along with most of the other electronics have been removed wouldn't that completely change how the AC is setup?

I understand your dilemma, with the factory manual you will be able to determine what is computer controlled and what is not, while your ac would not be controlled by the ecu, the ccr (constant control module) would control cooling fan and wide open throttle cut off switch, I would guess the ccr has been removed too.
The ac will require brackets from a 94-5 mustang V8 car and I would think the 94-5 hoses would work too.

I agree with karthief. Keep the mechanicals as close to stock as possible. You will have to do some wiring magic to make it work. It's probably not too complicated though.

I'm leaning towards just driving it through the winter and fixing up on other areas of the car then when summer hits just taking it to an A/C shop and forking over the money to have them do it.

Save some money and hunt down as many parts as you can first.
Did the po take the dryer hose off properly or cut it like the condenser?

Ok Buddy, I just ran the numbers here at the shop to give you an idea what a shop will charge you to do this work. This is under the assumption that the parts listed here are not present on the car now or they are unknown if they are functioning. This also is to restore it with an EFI system, any wiring or labor that would be needed for the swap to carb would be extra. Most shops like mine will tell you that if you are not replacing the Compressor, Drier, Orifice tube, Condenser and flushing the system that there will not be a warranty on it for parts or labor. Sucks but that is the case because something inside the lines can destroy it all. If you are paying someone to do it, get the warranty in writing..
