I'm having same problems.
Only driver side is blowing with warm air, rest of vent is just fine. It only happens when car is under hot sun in summer.
So, I tried to park the car under the shade when I park.
But when I drive under hot sun, there is nothing I could do, but sometime cold air come and go. It's very strange things. My dealer couldn't find problem at all when I brought the car for check up few times. Hope you will have luck to find a problem and be able to fix it.
