No worries at all! Good to know thank you. I am hoping it is just an o ring since those fittings don’t look horrible.
Should the shop be pulling a vaccum and testing to confirm that the system is holding?

Yes and I’d question the work of any shop that didn’t.
Agreed...at the very least. Vacuum assures that 15psi negative pressure doesn't cause a leak, and it helps to remove moisture from the system. I usually follow that up with a 24 hour pressure decay test with 200psi of N2 or CO2 in the system. I'll add a small quantity of refrigerant before I add the inert gas if I want to use the sniffer to find a leak.

Having to take it to a third shop. This shop just said that they can’t get bolt off and they’ll have to order and replace the entire line. At this point is possible to just cap these lines off so the front hvac works at least?!
My experience is that the aluminum they use for the rear connection fittings is very prone to challenges not only from corrosion but also from getting blasted with sand and gravel. I had to take my 200 to a shop that specifically deals with auto air conditioning issues as the Toyota dealer won’t work on it. The hoses are a very hard to replace item and sadly the shop said that al Toyota’s with rear air have the same problems - Sequoias and Siennas are common. The o-ring failure is not typical - it is usually the aluminum fittings themselves that fail. The shop fabricated a fitting and hoses to replace the fittings and it has worked for years without a repeat failure. Wasn’t cheap - it cost me over $3k to fix but the way the fixed it should prevent any future issues.

Did they basically get rid of the aluminum fittings and just hard pipe it? Like a section repair?
They made their own fittings but of much higher quality.
I was able to replace some really difficult to source Piper aircon hoses with the relatively new Aeroquip self assemble a/c hoses. Similar to their braided fuel lines but with ac oil compatible o ring seals. All available on Summit…pm me if you think this might be helpful.
2015 200-series, ~113k miles. The A/C failed last week. Warm air. A week before it happened I heard expansion valve hissing slightly, likely indicative of low refrigerant. The rear A/C line went per the dealer who is fixing it. They are saying they need some rear line replaced, not sure which one. Wonder if it will involve major surgery requiring replacement of the line going to the front of the vehicle.
It failed at about 1 month (and 8k miles) before the expiration of the platinum warranty that I regretted buying when I bought the truck in 2018. I never used it until now. Not sure if it will pay for itself but it looks like it might. I don't recall what I paid for it back in 2018, I think something around $1500?
It was first and last time I paid for an extended warranty. Ironically, the only other used vehicle I owned with an extended warranty was a 2012 Tacoma, I did not pay extra, the warranty came with the vehicle. A/C compressor had seized on it and was fixed under that warranty.
