A/c problem

I have a 2019 tundra platinum and my ac will work then I park the vehicle come back start it up and no ac. I may park again and sometimes it comes on and sometimes it won’t but eventually does come on later at some point. I did have dealer replace the blower in the passenger side as it went out. Please help me figure this out because dealer says can only fix when it happens and when I want to take it in of course it works
