2002 Dodge Durango Q&A
2002 Dodge Durango Question: Moisture in headlight housing.
Had a headligfht replaced last fall, and they found moisture in tthe lens housing. They drilled a hole to drain out any water, but the bulb has burnt out again. You can see moisture on the inside of the lens. Have not checked, but have been told that it is very expensive to replace this unit. It replacement my only option - Goldfinch
Some customers may report that on occasion, vehicle exterior lamp assemblies are fogged with a light layer of condensation on the inside of the lenses. This may be reported after the lamps have been turned on and brought up to operating temperature, turned off, and then rapidly cooled by cold water (such as rain, or the water from a car wash). Lens fogging can also occur under certain atmospheric conditions after a vehicle has been parked outside overnight (i.e., a warm humid day followed by clear cool night). This will usually clear as atmospheric conditions change to allow the condensation to change back into a vapor. Turning the lamps on will usually accelerate this process. A lamp that has large amounts of water droplets visible on most internal surfaces indicates a problem with the lamp sealing that has allowed water to enter the lamp. In this instance it is likely to report that moisture in the lamp is always present and never disappears. A lamp that exhibits internal moisture permanently should be replaced. - Johnny Mopar
