Headlight covers foged up?

Question

I have a 2001 chevrolet Malibu and my headlight housings are starting to fog up on the inside. How can can I make them clear again? Just as they were like new.

Answer 1

Sounds like your headlight gasket is bad. These gaskets (rubber seals, as they are commonly referred to) commonly go bad. You might try taking them apart and resealing them with clear silicone. Also check the rubber gasket around the bulb, as it seats against the headlight. That may be where the moisture is entering.

Hope this helps!

Answer 2

Since they are fogged on the inside, IE moisture from water, this is typical and not too easy to fix. Most of the time, save a cracked cover from a stone, the water gets inside from car washes and hitting puddles and driving through big storms. Some of the moisture will get in from just high humidity.

What happens in these new state-of-the-art clunker junker lights is there is a weep hole on the top of the light cover in the engine compartment typically with a little rubber tube attached to keep out the water that might come in from the front during rain or what ever.

This "weep hole" has to be there because these are not sealed beam head lights like the good old days and that big plastic thing just holds that small halogen bulb. When you turn on the headlights this bulb suddenly gets very hot and the air inside this light bulb holder has to go somewhere so it bleeds out of the weep hole. Well, not a bad design if you never have to turn off your headlights. The opposite happens when you turn the headlights off and they can draw in moisture or humid air. If you have them on while driving in the car wash or torrential down-pour this gets all kinds of moisture around them and cools them down which causes moisture to be drawn inside.

So, you will have no luck with restoring them to like new on the interior. All you can do is pop out the bulb and take a small hair dryer set on the low setting and heat up the front of the headlight until you don't see the vapor inside and then lay it so it blows into the hole for about 15 minutes or longer. Then put the bulb back in and don't look too closely for evaporated water residue; this way if you don't see if it isn't there. If you use the highest setting on the hair dryer you will be able to reach through the front of the headlight to dry it out as you will have melted a big hole through it or at least made it concave which might catch on and distinguish your car from all the others.

If the exterior is sand blasted or scratched from wear and tear, you can take some very fine emory cloth (like 400 grit or higher) or sand paper and polish this exterior surface. BonAmi is safe to use as a polish, too.

Good Luck!

Answer 3

There are some strategies right here: A. using some rubbing compound on a clean towel going left to good observed up by technique of hand waxing the lights. If mild hazing this could eliminate it. B. pass to an area factor shop and function them do the same technique yet with a severe velocity buffer. mild hazing. If yellowed, could nicely be scratched with fingernail, hazed over to the place no longer something works. Then this implies the exterior floor is long late to warmth of the lamp and the aspects and highway debris. the only thank you to repair it truly is step C or D. C. call a Headlight fix employer for maintenance, in many situations below $a hundred for the pair for an eternal fix back to OEM readability. (there is basically one interior america that i understand of) D. purchase new headlights at an arm and a leg

Answer 4

first, try polishing the outside. go to discount auto parts and buy a headlight polishing kit for $13.

it is a wet-sanding kit so you keep the sandpaper nice and wet.

it starts with 1000 grit sandpaper , then 1500, then 2000, and finally a very fine 2500 grit. it smooths it out like wet glass. then you polish it with the included polish kit.
