Where is the air conditioner internal circulation air inlet mark 508?

The air inlet of the air conditioning system with symbol 508 is located on the co-pilot's side, at the lower part of the glove box on the dashboard. The air in the car will enter the internal circulation air inlet, then pass through the air conditioning filter element, and then be sent to the warm air box or air conditioning evaporator after filtration, so as to realize the recycling of the air in the car. When the air conditioner is turned on in the car, if the cooling or heating effect is faster, the internal circulation mode can be turned on, so that the cooling or heating can be completed quickly.

Matters needing attention

In addition, the air humidity is relatively high in rainy days, and turning on the external circulation may cause the windshield to fog. At this time, adjusting to internal circulation can alleviate this phenomenon. Whether it is internal circulation or external circulation, air must pass through the air conditioning filter, so the air conditioning filter needs to be maintained and replaced frequently, usually once from 7500km to 100000km. If the daily driving environment is poor, it is necessary to shorten the replacement time.
