Audi q3 does not turn on the air conditioner, but only turns on the warm air.

Audi q3 can only turn on the warm air, not the air conditioner, because the heat of the warm air mainly comes from the water circulation in the engine cylinder, which heats the water and circulates it to the driver's side. There is a fan and a small water tank under the dashboard in front of the passenger seat. The water in the water tank is hot, and the fan blows out the hot air, which increases the room temperature in the car, so there is no need to turn on the warm air.
