A/C Heater Control
The Heater/AC Control are located inside the vehicle, their design and location depends on the vehicle and its model, but the most common design they come in is a round dial. This dial has two extremes, one side is for cool air, and the other side is for hot air. The remaining area of the dial is a lower intensity of the heating or cooling system. As it goes down from the extreme, these controls can be used to set the level of heat and cold air intensity that should be thrown into the vehicle. The controls are easy to handle, but the main button for AC and heater is the same. This button can be found separately, or in the middle of the thermostat dial. These controls can easily be access from the driver's seat, and are usually placed in the middle of the driver and the passenger seat, where the other features are present.
