I suspect sealer is involved and this band will never play in tune. Back to post where rayscopes said a one pound can of virgin 134a was used and only 1/4 of the can would enter system. That alone is messed up. Where did you find a one pound can? I've never seen one ever but who knows what might be out there? How are you sure only 1/4 of it went in - clearly you really don't know how much went in without wild equipment to weigh things. Every time you disconnect or connect you are contaminating something too. Either the system, hoses to equipment or gauges themselves.
This was the mother of all disasters for a sealer and best chance of working but would be your last try as if it leaked down or even evacuated later it wrecked everything including plain quick connectors of gauges or equipment like a plastic/glass when any moisture got to it.
Pic isn't going to show. That stuff was so bad it would clog service ports so came with its own one use tap to throw away.
You might see it in your "O" tube that is trashed.
Evaps on these and other models by Chrysler were way too common IMO. This crap would be a chance to fix one without replacing the part now not seen or sold anywhere TMK.
Something like that or a prior "grenaded" compressor as Hammer mentioned with hard debris could explain why this is not cooperating and bizarre observations. Speculation only on my part but know that product could and did ruin anything it touched including your equipment all become dump food,

Here's one full of sealer that I took out of a car myself

Update: 97 Jeep Wrangler 4.0L No Charge

The condenser is plugged. I tried flushing it in both directions with an aerosol a/c flush can. It must have been plugged when I got it unless the compressor happened to take a crap. I guess I'll find out when I install the new condenser.

Condensers don't clog themselves but rather catch debris from compressor burning out or something added that totally doesn't belong in the system.
TMK you really can't effectively flush out a non tube and fin condenser and new one will just do the same thing if you don't fix the cause at the same time,

That condenser was the replacement, right? Probably someone's core....LOL
I had one that was partially restricted that was the replacement on a 05 Hyundai Sonata. The ac system worked great until it got hot outside and the head pressure went to the moon and would kick out the high pressure switch. Removed the drier bag and look up inside and you could see parts of solder wedged. Low quality manufacturing = low quality part. Don't feel bad, it happens to all of us. We just wanted to make sure that you had performed all the correct service procedure steps. We get a lot of DIY in here that don't know anything about AC getting their hands on stuff, so I get skeptical sometimes.

So the line from the compressor to the condenser had some oil in it but no other debris. How do I determine if there is a problem with the compressor? Is there a way to test it or do I just put it all back together and hope for the best?

Ok, I'm trying to determine if I have the proper charging procedure: when I put in the 1st condenser and the hi pressure went super high I had only charged though the low side port. It wouldn't take anymore with the engine off so I started it and shortly after the hi pressure went to 400-500 psi so I quickly turned off the engine. Should I have turned the can upside down and charged through the hi port with the engine off first? Could not doing this have caused the condenser to get plugged?

It's time for this to go to a professional that specializes in AC.

I thought this was a DIY forum? Believe it or not I've been screwed by the professionals and have a lot of mechanical experience and training myself. I also do better work than a lot of "professionals" and there's no guarantee that the professional I take it to has a clue either. Therefore, as a former professional, what would you do next with the given information?

You do realize that the people that are helping you out here are professionals right? We don't know who you are referring to as professionals, but there are many technicians out there that have been repairing and servicing ac systems on all different makes and models successfully. Takes a lot of money, training, and experience to become proficient. Goobs charging systems with can taps, no scales, and using system pressures to fill a system are not what I call professionals.
I agree it is time you swing into a professional licensed and insured repair shop that specializes in AC to have a look at this thing.

As a professional would you agree to flush all components and replace the accumulator? If it was your vehicle would you open the compressor to look inside or test it somehow or would you just replace it?

Rayscopes: We are current or former pros and trying to help you including saving you from endless problems from lack of proper equipment or experience/training in what can go wrong. A/C is an area where one thing wrong takes out other parts new or not down the line such that you are worse off then not touching it.
Long thread already so sorry for repeated things noticed. It has debris already noted most usually from compressor failure or a combo of that and a sealant that may have been used. Know that if system operated and no proper cooling it's starving the compressor of lubrication which may not have been the issue to begin with. The training is rather extensive and even just enough equipment is expensive as well. The best of all of it is outrageously expensive so it does cost to send it out.
Problems with another before can happen in anything or trade. Unscrupulous professionals can exist in any trade as well and wrong in any of that sort of thing.
I too suggest you seek out proper professional help and cut losses of so far. IDK for sure if you can flush out a condenser on this exact one and if solvent isn't all out and dry it would likely self destruct all over again.
So the help is to suggest for this case is now to find the right place and tech with the know how. Motor vehicle A/C just isn't very DIY friendly,
Tom

You need somebody on-site with the know how to recognize what the issue is here. There is only so much that can be done by remote control.
You've been running in circles for a week now and it's time to give it to someone that knows what to look for.

Actually YES! If another shop with techs I would know had more or better equipment I would seek out help. I don't and didn't own a detector for contaminated refrigerant for example.
Quite a few shops just avoid A/C where I am as many folks with an older vehicle just wont fix it for a short season and just use another vehicle for the few nasty days you would really want or need it.
The shops (NE USA) don't really like wasting room for all the stuff for seasonal (usually) work nor heat shops enough in Winter for knowing the system works properly when finished. The collision biz when A/C parts were broken get either sent out or just left in a safe state of low known charge disabled to operate till later or by agreements with shops, customer and insurance if involved.
Been there done that too buying a used vehicle in Winter you make in writing that the A/C will work properly when you can know and test it as well,

Ok, let me summarize, I have a new evaporator. I will be installing a new accumulator, condenser and orifice line since the quick disconnect is corroded solid (I flushed the line out and didn't seem plugged). That only leaves a short suction and high pressure line and the compressor. What would you do if I brought all this to you?
