Precautions for cleaning a car's air conditioning system are as follows: 1. When using cleaning solution or foam, ensure the air conditioning drain is unobstructed to prevent water accumulation that could damage electrical components. 2. After cleaning, open the car doors and preferably air dry for one hour. 3. Upon completion of the operation, use diagnostic equipment to check the system computer for any fault codes. Verify all functions are operating normally. 4. Replace the cabin air filter after cleaning. Generally, it's recommended to replace the cabin air filter at least once a year. The replacement process for electric vehicle cabin air filters is the same as for fuel-powered vehicles. Detailed steps for cleaning a car's air conditioning system: 1. First locate the air intake vent connected to the air outlets, typically positioned at the lower right side of the windshield or beneath a central cover panel. 2. Set the air conditioning fan to maximum speed and activate the external circulation mode. 3. Open the intake vent cover using hands or a screwdriver. 4. Connect the tube attached to the cleaner and spray into the intake vent, reapplying every few seconds (rather than continuous spraying) to allow circulation. The blower will draw the cleaner into the air ducts. Change circulation modes to ensure all ducts are cleaned. 5. After 15 minutes, turn off the air conditioning. The cleaner will drain out with condensation water. When no more condensation flows from the ducts, turn on warm air to evaporate residual cleaner inside the system, then leave windows open for ventilation. 6. The car's air conditioning cleaning process is now complete.
