I've been reading through most of the replies in this thread regarding the heater fan problem.

Recently I noticed that the heated air from the vents suddenly turned cold after around 1/2 hour into the journey. To get the heat air back, I need to increase the temperature to the highest (H1). The fan speed is kept low throughout. Does anyone knows what's wrong with my heater/fan?
I would appreciate if someone could point me in the right direction regarding my problem.
Normal operation of EATC (not too subtile) firmware, especially in sunlight. Its compensating for the possible temperature gradient due to measurement point at knee level, and greenhouse effect of windows.
If you don't like it or feel its over compensating, close the vents manually ?
