What to do if the headlights of a new car fog What to do if the headlights of a new car are fogged u

It may be that the dust cover of the headlights is broken or the seal is not good, open the dust cover of the headlights, and turn on the headlights, the water mist in the headlights begins to disappear after 10 minutes, and it can disappear completely after 1 hour, if it disappears, don't worry, but if there is still water mist, you must go to the professional after-sales service station to check, it must be badly sealed or there is a place to break! There are three conditions for fogging and water leakage: 1. moisture; 2 is the temperature difference:

3 is an attachment; (When the cold air outside intersects with the hot air in the headlights, both are not discharged and discharged in a hurry, then the cold air will stay in the headlights to form moisture, the new lights look smooth on the surface, but in fact they are not, the new lights will slowly age in the process of use, but become smooth, on the smooth surface, no matter how the moist air intersects with the hot air, fog and water droplets will not be formed, so this is the reason why the new headlights will fog up) I hope it can help you.

It is normal for headlights to fog up. Because the rear cover of the headlight structure has a rubber tube for ventilation and heat exhaust, it is also because the moisture of the rubber tube air enters the headlamp and adheres to the lampshade to produce water mist, which will cause water droplets in serious cases.

Treatment of fogging of automobile headlights: 1. The moisture in the air will enter the headlights through the ventilation tube and attach to the lampshade, and with the gathering of water vapor, water droplets will flow down the lampshade; This situation is mostly caused by large temperature differences, which is most likely to occur in winter and rainy seasons; 2. If the headlights are only formed below and the top is still very clean, then it is usually a normal situation of fogging, it is recommended to turn on the headlights frequently, and dry the water vapor inside by turning on the lights, which can be dissipated after a week of normal use, or you can idle in place for a long time to turn on the headlights or connect the charger and turn on the headlights; 3. In addition to changes in the weather, human factors will also make the lights foggy, such as vehicle wading, car washing, etc.; When the vehicle wades in water, because the engine and exhaust system itself are relatively large heat sources, rainwater will form a large amount of water vapor on it, and along the ventilation pipe, part of the water vapor will enter the headlights; 4. If the water accumulation inside the headlamp is serious, then it should be disassembled, and the lampshade should be opened, and after drying, check whether the surface of the headlamp is damaged or may leak.

The solution to the fogging of the headlights of the new car is as follows: 1. The defogging method caused by physical phenomena causes fogging As long as the headlights are turned on normally every day, the fog will dissipate in about a week; 2. Defogging method caused by water ingress: first keep the engine idling, then open the engine compartment cover, then unscrew the dust cover or dust cover, continue to turn on the headlights for about 30 minutes, and then use an air spray gun to increase the airflow speed in the lampshade until the dehumidification and defogging are completed.

At the same time, be sure to find the place where the seal is not tight, clean it and dry it, and then reseal it; 3. Turn on the headlights to dry the fog inside, then turn off the engine and turn off the headlights, and pour water on the parts that may preliminarily judge that there may be water seepage, such as the waterproof cover or waterproof cover, if there is fog in the headlights after a few minutes, then it can be judged that the water is not tightly sealed here, otherwise there is a problem with the bonding between the lampshade and the lamp base. Once it is found that there is damage or the adhesive is not good, it should be replaced or re-glued immediately.

1. Check the cause.

To determine the cause of the headlights fogging, first rule out whether there have been recent cases of driving in rainy weather, wading in water, or having washed the car. If you are driving, wading, or washing your car in rainy weather, then the fog from the headlights is likely to be caused by water ingress, so check it first.

2. Check whether the headlights are damaged.

In normal driving, you may not be paying attention, and you may be crushed by other vehicles and collide with the headlights. Or when the car is parked in the parking lot and you are not at the scene, the dust cover of the headlight has been scratched, so the lampshade is damaged, there is a crack lamp, etc., check it carefully first.

3. The lampshade is not tightly sealed.

If the headlight dust cover is not damaged or cracked, it is likely that there is a problem with the sealing gasket, because the sealing is not tight, resulting in water seepage from the headlights, resulting in fogging. This needs to go to the professional maintenance department of the car to check and deal with it.

4. Water condensate.

If it is not the cause of rain, wading, or car washing, it is the water condensation caused by the temperature difference between cold and hot caused by the climate. Just like when we drive normally, when the outside temperature is relatively low and the temperature inside the car is high, condensation will form on the windows. Generally, this situation occurs when we use the lights, but this situation is only occasional, and after the heat, the fog in the headlights will slowly dissipate.

If this phenomenon always occurs, it is still a problem with the lampshade and gasket, which needs to be further investigated.

5. Defogging method.

If there is a slight fog in the headlights, you only need to turn on the headlights of the car and bake it, and the fog will slowly evaporate when it is heated.

6. Sunlight exposure.

If the fog in the headlights is heavier (to be exact, it is water), then it is more troublesome to rely on the light of the headlights to bake, it is better to drive the car to a place where there is sunlight, and use the ultraviolet heat of the sun to slowly evaporate the fog of the headlights.
