Recently when I've been stuck in traffic for more than 15-20 minutes, I start getting lower and lower temperature through the vents and A/C fan increasing speed because the sensor can tell it's getting colder than the chosen temp. Selecting "Hi" doesn't help. When this happens I've noticed the coolant temp rising slightly from the usual 8:30 to 9:00. When the car starts moving again and the radiator gets some airflow, the heat comes back within a minute or so.
I'm pretty sure it's not the cabin temp sensor and the coolant isn't too cold, quite the opposite. Anyone have some suggestions what the problem might be?
