2015 bmw 640i a/c blower turning off

What is your question?

Hello, i have a 2015 bmw 640i gran coupe, recently my a/c turns off after a couple minutes, then come on for a little, and back off...Lights on a/c dash stay on,.You move the fan speed up and down, temp up/down, a/c on/off, heat on/off... but yet no air, then it'll go on for a little and turn off..., as if fan turns off completely, u feel the diffrence in engine idle(when it goes on and off...)...now I'm noticing my temperature in the car is 1-2 little sticks passed half way sometimes, but the a/c issue happens even before temp reaches the half way point...i also started hearing a small bearing/tensioner sound from belt area...car has 60k miles belt needs to be replaced as well looks a little worn now that i notice, but shouldnt turn a/c- Fan off

What makes this problem better or worse?

Hot weather seems to make it worse
