Moisture inside headlite and tail light assemblies--2002 Lincoln

On my 2002 Continental, beads of moisture have collected on the lens of my right front headlite assembly, appearing on all portions of the lens, and a small pool of water has collected at the bottom of the innermost segment of the assembly. I presume this is leaking in from rain and water thrown up from cars ahead of me when driving in wet conditions.The headlite lens itself is not cracked or broken. I appear to have similar moisture collecting inside the left rear tail light assembly, which likewise is not cracked or broken. How can I locate the sources of these leaks annd repair them?

I would dispute the answer about the bulbs and the gaskets. I see this condition all to frequently, what is really happening is this : The method of sealing the lens to the reflector housing is the culprit, assuming that there are no cracks in the lens/reflector assembly. The mastic, or glue, if you will, becomes hard, and it no longer seals the lens to the reflector, and thusly admits a minute amount of water. What I would wo would be to remove the headlamp assembly completely, and examine it closely around the circumference for separations in the glue between the lens and the reflector. If any compromises are found, a good cleaning of the mastic and the reapplication of clear silicone usually stops water entry in small areas. If the separation area is large, I would then suggest separating the lens from the reflector, cleaning all of the mastic out, and re-glue the lens to the reflector with a 2-part epoxy, such as "JB Weld". Please do NOT rate this solution if you want to continue conversation on your issue; applying a rating will cause my input to you to be terminated, you will no longer be able to see more posts from me. Thanks for allowing me to assist you on this; I hope to hear back from you.

    To properly locate the sources of the leaks, removal of the headlamp assembly, and submerging it in water, lens face down, with some compressed air into the bulb hole will display air bubbles in the water bath, outside of the lens area.

    Sometimes, the crack in the sealer is very difficult to discern by the unaided eye.

    I understand.

    Please advise me it the bulbs do indeed have "replaceable gaskets"; and if the area behind the headlamps, where the bulbs insert into the reflector, is "wet" when you are driving in rainy weather. Thanks.

The source of the leaks is actually the bulbs themselves. there is a gasket around the replacement halogen bulb that probably needs replaced the next time that you have a bulb go out.

I have moisture inside my headlight on my 2007 gmc denali. will i have to replace the entire assembly. The lamp is out, could that cause the moisture. Or does the moisture cause the lamp to burn out.


{: ) Some exterior lamps, such as cornering, turn signal, backup, headlamps or tail lamps may exhibit very small droplets of water, a fine mist or white fog (condensation) on the inside of the lamp lens. This may be more noticeable on lamps with "multi-lens" designs and may be normal during certain weather conditions. Condensation occurs when the air inside the lamp assembly, through atmospheric changes, reaches the "dew point". When this takes place, the moisture in the air within the lamp assembly condenses, creating a fine mist or white fog on the inside surface of the lamp lens.
Most exterior lamps on General Motors vehicles use a vented design and feature a replaceable bulb assembly. They are designed to remove any accumulated moisture vapor by expelling it through a vent system. The vent system operates at all times, however, it is most effective when the lamps are ON or when the vehicle is in motion. Depending on the size, shape and location of the lamp on the vehicle, and the atmospheric conditions occurring, the amount of time required to clear the lamp may vary from 2 to 6 hours.
Completely sealed headlamp assemblies (sealed beams) are still used on a limited number of models being manufactured today. These lamps require the replacement of the complete lamp assembly if a bulb filament burns out.

If moisture or droplets appear after being exposed to rain or washing, you can try putting some weather seals on the edges where you think the seal is poor. Check also the headlamp caps. In any case, if the moisture doesn't clear no matter what drying approaches, better replace the assembly.
The bulbs won't cause the moisture, but it is possible that an accumulated moisture on the bulb itself can disable it, although rare.

I have moisture on the inside of the headlight lens. How can I get rid of it without buying a whole new headlight lens assembly?


Just a suggestion, remove the light assembly, remove one bulb, blow air into the unit, see where the air leaks out, seal it with Goop. Quick and easy.

How do you remove and clean out the headlight assembly from a 2002 Honda Accord


I gather that you mean taking out the lens, and cleaning the inside. This piece is glued to the plastic assembly, and is very easy to break trying to take it apart. Most of the time, the problem is just moisture inside. On a hot sunny day, take out the main bulb ( no need to dismount the assembly) and let it sit for a couple of hours, and most of the moisture will vent away. If it is just the right headlight that gets fogged up, you might be losing coolant from overfilling. Also make sure all rubber gaskets on the bulbs, seat firmly against the headlight assembly.

1999 ford taurus with moisture in the headlights


Most headlights lens are sealed up to prevent this problem. A broken seal or a crack somewhere opened up to let in moisture.
You can drill a small hole on the lowest part of the plastic headlight housing to let the water drain out. Or, replace the plastic headlight assembly with a new sealed one.The plastic headlights turn yellow and cloud up over time (not because of moisture inside, because it's plastic getting ruined by the weather and the sun). This problem reduces headlights from putting more light on the road.
The only thing you can do with moisture inside the headlights is to drain out the water that builds up. The seals on the headlights are bad right now and are going to keep letting moisture in. I would replace the both headlight assemblies for new sealed, clear ones.

1998 Lincoln continental won't start, tries but just grinds. Just washed the car two days ago lots of water got under the hood as I chased pine needles out of the base of windshield.


If the car has a distributor cap (some lincolns have a distributorless system) the cap probably has moisture in it. Spray a little starter fluid around the cap and wires to dispel any moisture.

Tail light bulb needs replacing


You must remove the cargo carpet lining from inside the trunk in the corner behind the taillight. Five nuts removed the sealed light assembly. Once removed, the bulbs are behind quarter turn sockets.
