It's too bad no one was able to answer this question. I have about the same problem. I am mostly annoyed that the air from the HVAC system is either very cold or very hot. I can't find a middle ground between hot and cold. It can be very unfortunate at times. I have to turn on the heating at regular intervals on cold days to avoid getting fried inside the cabin. I've asked a lot of car enthusiasts I know. None of them could help me. My last hope is a car mechanic friend who took a special HVAC course at https://www.hvacschools411.com/by-state/. I tried many options, even replaced the AC amplifier, which was quite expensive.
Anyway, you asked about it in 2019. Were you able to solve the problem?

Tell me, what else do they teach at that school you recommended?
