SERVICE INFORMATION
Occasionally customers may notice water vapor or fog in the exterior lamps. This is generally NOT due to a defect.
The following information, illustrations, and flow chart are provided to help you in determining if an incident for water/condensation in the lamps is
normal or not.
All current exterior lamp assemblies are vented to the atmosphere (not sealed).
^ This is necessary to allow for expansion and contraction of air from temperature "variations" (warmer or colder) without damage to the lamp.
^ Moisture in the air sometimes "travels" into and out of the lamp assembly through these vents.
^ Certain environmental conditions may cause moisture to condense.
^ The fogging/cloudiness should disappear over time when the lamp is in a dry environment.
Fog may temporarily form inside the lens of the exterior lights based on environmental conditions or sudden temperature changes (such as in a car wash).
This is normal. See Figure 1.
NOTE:
This condensation can appear anywhere on the outer lens, typically at its coldest location.
