This thread is two years old, but I'm now experiencing this issue. North Texas had a lot of rain today, it was mid 80's in the sun and low 70's in the rain cooled areas. Near 100% humidity.
After driving about 30-40 minutes into a 1 hour drive on the highway I noticed the interior was not as cool, and airflow was restricted. I recognized the problem right away, having read this thread back in 2023.
It happened on the return trip, too. If I turned the system off and waited about 5 minutes and turned it back on, it would blow cold air right off, and worked well for another five minutes, then freeze up again.
Guess I need to go in and get my refrigerant removed and reloaded. I just ordered a new cabin filter as well.
Coincidentally, I've noticed a moldy smell when the AC first comes on, at start. A couple weeks ago I removed that thermistor and sprayed a can of auto coil cleaner (Nextzett Klima Cleaner Pro) in there. It drained out the drain hose quickly, as expected. I re-inserted the thermistor and locked out back down. I suppose I could have damaged the thermistor, but I don't think I did.
This really is a common issue in these cars.
