Same problem here.... air con works fine and cool from Engine start.... Fans slows down after about 15 mins, turning the fan manually does speed up the fan but not the actual cold air flow... turn on the front window defog button OR turn off the A/C button for a short a while (1-2 mins), then press the AUTO button it will work fine again. But only for another 10-15 mins and the problem returns.

Fan has been replaced a couple of month during the previous maintenance, I've also just replace the FSR/FSU.

I'm also interested to know what can be done next before I take it to the shop again. Temp sensor? Where is it located?

I normally switch OFF the air recirculation, does this contribute to the problem?
