First, thank you very much! No, it doesn't 明显跑偏, just a little. Is it possible that a car was crashed but still looks very good, I mean, can't find any 撞过的痕迹？2。it's not the 出风口that flows warm air, but
I found the warm air is from the place near my feet.
3. so the pointer of the 水温表should points near the middle of the gauge.
