Done a lot of reading on the internet recently, and I can't seem to find a concrete answer on this.

Here's the deal: I had plans to tuck & relocate my AC lines in the future, as a majority of them needed to be moved/modified beyond what was capable with the OEM hard lines while installing my supercharger setup. That said, I ended up removing a majority of them instead and going without A/C in the interim. I just recently removed the A/C lines from the compressor itself a couple months ago, and unfortunately I left the ports open. The car stays in the garage, and hasn't really seen the elements. And I'm assuming the compressor hasn't been running "dry" because as far as I know the compressor isn't actually doing anything internally if the clutch isn't engaged, correct? Which it won't, because the lack of pressure in the system won't allow it to kick on.

What I want to know is if I should plan on straight up replacing my compressor for this oversight on my part. Since I need to build all of these A/C lines I'll just toss in a new/rebuilt compressor as well while I'm in there if that's necessary. Realistically is there anything I can do to remove the current compressor and service/salvage it before ultimately trying to run it and potentially damaging it? I'm just having a hard time understanding how the compressor can be completely shot if it hasn't seen much moisture since the pipes being removed. At most, I'd say maybe some particulates from the road may have found their way inside, but I couldn't see the internals rusting to shit instantly, but I'm not an expert so that's why I'm asking.

Ideally I'll remove the compressor and have it serviced and/or rebuilt, if not, I'll buy a used one in good shape, or, if it's okay to attempt to use this one, I'll do that. I'm considering replacing the condenser as well; I already have a new dryer. The car only has 54k miles on it so ideally I'd rather not scrap this original compressor since it has a lot of life left if it isn't already ruined/can potentially be saved.

 

I'm no mechanic, but I would attempt to use the one you have.

 

Run some ac flush through it and let it ride.

 

I would agree to the above, run some flush through it, evac and recharge it and you should be good to go.

 

My dad is a mechanic so I asked him here since he has about 50 years more experience than I lol. He said obviously not good but if it were his or his customers car he would recommend the following: Flush (he uses Duraflush/BG refridgerant oil. Do not flush the compressor, replace the dryer. Make sure condenser and evap are flushed well. You will need a way to flush it though.

He also will not use the flush that comes with any of the kits. He uses Duraflush as he has never had a single issue vs many issues with some of the flushes that come with rep kits.

Then after flush, charge and use it. Likely will be ok but no guarantee with it being left open for a while.

 

If there's no oil in the compressor, and the compressor ports have been exposed, you will likely have some surface rust in the scroll. Add some oil, turn the compressor by hand, make sure it's only making pumping noises. Then dump out that oil and refill it to the proper amount.

AC flush is basically just acetone and a little mineral oil.
