It is not unusual for AC to fail suddenly. I have a compressor failed on me all of a sudden when the metal valve inside the compressor broke and jammed the unit. Luckily the kilma relay will kill the AC when it senses the shaft is not turning. Your problem doesn't seem to be the compressor. Good luck.

I haven’t checked pressures yet. Apparently I loaned out my ac manifold to my dad and now he can’t find it. I’m gonna try to take it to a shop Monday. It’s so hot outside to spend time diagnosising things
Touching the ac hard lines .. one is lava hot and the other is ambient temp. Ac compressor seems to turn on as normal from the climate control panel. Is there a switch or something that would block that line? Comparing it to my other w124 the line near the master cylinder should be cold.
