C5 ac help

I’ll keep it short and concise. About 2 weeks ago I started having this weird AC issue and I’m hoping someone can help. On the hottest day of the year so far my ac stopped working. What’s weird is the defrost and air recycler setting don’t work, but the fresh air one does (kinda) the faster I go the more air comes out of it. (I’ll be it still not very strong)

Now I know what you’re thinking “it’s just pulling are from outside” but it’s not regular air because it’s still icy cold. Well what’s even weirder is the other day the temperature got below 65 in the morning for a couple days (including today) and all my buttons worked. The air recycler setting was blowing perfect. I noticed when it warms up to 70 degrees or higher nothing works again. I don’t know if it’s my blower motor, my ac vent actuator, a fuse, or a relay. It’s just really weird and I’m at a loss because I would imagine if one of those were the culprit it wouldn’t work period, not just when it hits a certain temperature outside. I’m posting here because I’m hoping someone has had the same problem and can point me in the right direction.

Also side note my heat does not work, even on the mornings when it’s 65 degrees or less and my ac is blowing perfect. When I switch to heat the air just stops blowing which makes me think its the vent actuator, but it not blowing at all when it’s warm makes me think it’s the blower motor. Who knows maybe it’s both🤷‍♂️
