Yeah, my AC's been acting up as well. I think the main issue is just the blower motor regulator, but it's also not as cold as I'd like. There's a good manifold set on Amazon for like $50; checks both high and low pressure ports for you.
You know, it's actually not bad to work on at all. Back then Mercedes really went out of their way to make things easier for the mechanics (unlike Audi, where a timing chain replacement requires you to pull out the entire engine). The big issue is just that there's always something that needs work. The engine and transmission are very reliable, but people fall behind on maintaining all of the other features, so you see a lot of older S Classes on Craigslist for like $800 because half of the car no longer works and they can't be bothered to fix it anymore. If you don't do your own work and have to rely on The Dealer, maintenance on an S Class runs between $4k and $6k a year. Even the oil change is $250 at the dealer. You get a lot of young people buying these ten year old Mercedes for under $10k, and they have to sell them within a year because they can't even afford a brake job.
>alternative options for IB webhosting
The problem is that the game has changed in the last few years, and none of that matters these days. If you got with a big major host, they'll drop you on principal. If you go with some tiny reseller host, they might want to keep you, but leftists will just write to PayPal, Stripe, etc and suddenly your host's business is in danger. Faced with that, they of course will drop you. But even if all of that fails, they can just write to your domain registrar, your DNS host, etc and get all of that dropped. Suddenly your site is inaccessible. There isn't a clearnet solution that has any value today. Tor is okay I guess, probably more hassle than its worth. For right now, it'd be best to just see what happens with anon.cafe long term.
>think the compressor simply lost all of its freon
An AC is a closed system, and the refrigerant would last the lifetime of the unit if it never leaked. Without a leak, it will almost never run low on its own. Leaks are extremely common though, especially in the evaporator coil. If you run the AC on a low charge for any length of time though, you may be out the entire compressor. There's a dye test you can do pretty cheaply to see where it's leaking, if the charge is actually low.
