Clean air vents and the cab of dust and dirt frequently.This is not only good for the beauty of the car, but also good for the health of the driver and passengers.3. Check that the refrigerant is sufficient.This can be measured by feeling the temperature difference between the inlet and outlet lines of the dryer, or by measuring with the manifold pressure gauge.4.
