How to Adjust the Cadillac Air Conditioning to Heating Mode?
1 Answers
Method to adjust the Cadillac air conditioning to heating mode: 1. After starting the car, wait for 5 to 10 minutes until the water temperature rises to the normal level; 2. Press the off switch on the center console to turn on the air conditioning and adjust the circulation mode to internal circulation; 3. Press the red button to switch to the heating mode. When the car air conditioning is in cooling mode, the engine drives the compressor to operate. The compressor continuously compresses the refrigerant and delivers it to the evaporator. The refrigerant expands and absorbs heat in the evaporator, thereby cooling it. The cooled evaporator then cools the air blown by the blower, allowing cold air to be emitted from the air vents. The heating principle of car air conditioning is simpler. During heating, the high-temperature coolant from the engine flows through the heater core, and the air blown by the blower also passes through the heater core, resulting in warm air being emitted from the vents. Most car air conditioning systems use R134a refrigerant, which needs to be replaced periodically. Failure to replace it in time can affect the cooling speed and effectiveness of the car air conditioning.
