See how to clean the air conditioning, filter housing, evaporator and air conditioning outlet very carefully. 1. WE NEVER USE FOAM VENTILATION – Risk! 2. WE EXTEND THE FILTER FILTER (we exchange for a new one every year) 3. EXACTLY CLEAN THE BOOTS AND BRUSHES from insects, leaves and dust, from EVERY corner – CAUTION! 4. Pour water with liquid into the filter housing (syringe, sprayer) and it should quickly drain under the car through the drain in the evaporator casing (the car is going to stand up straight), if it does not drip or very slowly, then we have to underneath the car, turn off the outflow, yes as on the film below and retry, the water is quickly drained. 5. We spoil the foam or other means for evaporating the evaporator (not to refresh!) Eg BIZOL C30, WURTH, preferably 3 times well and set the airflow to 1, close the housing without filter and leave for a few minutes, the agent starts working, then open and again, we spoil the entire evaporator and filter housing 3 times. 6. Clean the whole filter housing with a cloth to dryness and when everything is dry, insert the NEW cabin filter, preferably with the addition of activated carbon, eg DENSO. 7. We enjoy perfectly cleaned air conditioning, the stench disappears and if we want to complete the cleaning to the ideal, we can perform the service OZONOWANIA the interior of the vehicle in a workshop or at a friend who has such a device, it’s a cherry on the cake. See the guide and perform cleaning in your car, and the effect should be very good.
