So basically HVSC Tecs can’t find the leak, I asked for them to preemptively change the little fill valves and they wouldn’t.

Pretty much system stays filled all summer.

Wisconsin 1 day is hot, next cold, next hot again in the fall.

Last 3 years when that happens I find the ac system is empty and won’t engage.

Any ideas what this could be?
Only common failure on this car is bad o-rings.
