What kind of cleaning or maintenance does Vitera automobile air conditioner usually need to do? ?

In general, there is a pollen filter at the air inlet of the automobile air conditioner, which is used to prevent the dust from entering when the automobile air conditioner circulates outdoors. When cleaning the air conditioner, remove the pollen filter, inject the foam cleaning agent into the air conditioner from the air inlet, and close the air outlet of the air conditioner to prevent the foam cleaning agent from flowing out of the air outlet. After these two steps are completed, start the car, turn on the air conditioner, and let the foam cleaning agent circulate inside the air conditioning system. This step will last for several minutes to ensure that the foam cleaning agent circulates to all channels of the air conditioning system. About 5 minutes, turn off the air conditioner and turn off the car. It won't take long for the dust to flow out of the cabinet from the air conditioning piping system.
