Could it just be the compressor belt? I assume you're getting some cool air but not much. There aren't any other moving parts so the only other option is that the flow is being blocked by something.
No squealing. Hard to say regarding temp. Hasn't gotten hot yet(tomorrow will be), so the air kinda sorta feels cool, but I think it's ambient temperature. When I checked the pressure, it showed it being overcharged. I took it for a short drive with the ac on, and the pressure was even higher.
I've never really fooled with ac(hardly ever even had it), so I'm not that familiar with repair. I don't enjoy car work, but I enjoy it more than dealing with the jokers that do our auto work. I'd rather try to fix it myself than be without a vehicle for a few days, and getting back still screwed up.
It was neglected by my boss, so I need to do a bunch maintenance that was never performed, and since it's a bmw, everything is weirder and more expensive. Something as simple as changing the sparkplugs is a pita. I'll need to have a valvecover gasket on hand, because I may find leaked oil, and a plug change is halfway towards a valvecover change. It does leak oil, but I can't see where with all the stuff in place.
Another task to add to the list of stuff I don't feel like doing...
