Also just to note, my A/C during the summer was also kind of spotty. It would blow but not also very cold and would take a while to blow cold. Not sure if it’s related or not.
problem #1 my heat is not working kind of. It was working
I haven’t noticed there being a difference but I’ll be on the look out for that tomorrowdoes the air flow speed/power seem to be the same in all settings? feet, vs body, ve defrost or does it seem to blow harder on defrost than all other settings?
I will have a better idea if the actuator worked or not in the morning 1plus drive at 5am in 28 degree weather should give me a good idea. If that’s not the culprit what would be next?Hose in in the correct place -- but as stated before you do not use that valve in the winter -- only OFF and Max AC
Most likely you have other problems in the vacuum system -- we need to address your current problem first
pick up a hand held vacuum pump that has a gauge from someplace like harbor freight or amazon -- for testing , later
