Condensation in the Headlights: Should Graduates of Auto Mechanic School Be Concerned?
September 6, 2018
Moisture or condensation forming in the headlights is something not many car owners often wonder about, but it can be a common incidence that occurs during the course of driving in humid or wet weather conditions. Water usually permeates through cracks or damaged seals around the cover and from the disparity in temperature outside and inside the headlight.
Depending on the construction and material of headlights, when the temperature drops, even completely sealed headlights tend to mist up and fog. This is due to the heat produced once the headlights are turned on for a long period and then cooled when the vehicle is no longer being driven. Graduates shouldn’t be troubled when faced with newly-trapped liquid, as there are a number of ways to deal with misty headlights.
Gathering the Tools Needed to Perform the Necessary Repairs
Depending on the extent of the problem, condensation in the headlights can be a minor or major repair. Under minor circumstances where the headlight is covered with mist, professionals only need two tools to solve the problem: a screwdriver and a hairdryer. First, open the hood of the car in order to gain access and remove the headlight cover. Once the screws have been removed, point the hairdryer at the top of the cap in order to evaporate the water.
It is important that students in an auto mechanic school be mindful not to overheat or melt any exposed wires or tubes surrounding the headlight when applying heat. This can cause an additional and more serious problem to repair. For the water to dry, the process usually takes around 30 to 40 minutes and it is recommended that breaks are taken in between to ensure the parts stay cool and the plastic components, or any other parts, do not burn or damage in the cap opening.
Condensation in the Headlight May Require Further Repairs
Under more serious circumstances where there is frequent water buildup or an abnormal amount of moisture occurring in the headlight, this will lead to auto repair procedures that are not as simple as the procedure mentioned above. If the headlight cover, sealing, or the rubber gaskets sealing it to the body are cracked or damaged, it could mean replacing each individual part.
If, for example, the headlight housing is cracked, this means that the entire unit needs to be replaced. This instance may require removing the front bumper in order to gain access to removing the headlight.
Other Precautions Taken by Graduates of Auto Mechanic Colleges
Students who attend mechanic colleges acquire the knowledge to consider and inspect further reasons that may be playing a part in a vehicle’s dilemma. When faced with condensation in the headlights, rather than begin evaporating the excess water right away, it is important to verify whether other external factors are contributing to the problem.
Professionals may want to check if the headlight vents are obstructed as this could potentially lead to a build up of moisture, fogging, or misty issues in the future. Vents can be blocked by road debris, dust, and other obstructions, but can easily be cleared by applying compressed air or manually cleaning easy-to-reach places. Once these steps have been effectively executed, the headlights should be able to work well again.
