Info - Headlamp Condensation

DURING CERTAIN AMBIENT WEATHER CONDITIONS, CONDENSATION THAT FORMS IN THE HEAD LAMP, THE FOG LAMP OR THE DAYTIME RUNNING LAMP (DRL) HOUSINGS AFTER THE LIGHTS ARE TURNED OFF CANNOT BE PREVENTED. This condensation is a uniform covering of fog or small droplets less than 1 mm (0.04 in) in diameter. This head lamp assembly uses a new venting technology which even in the worst weather will allow the lens to clear within one hour of activating the lamp. This is a normal condition and does not justify replacement of the assembly.

If the condensation inside the lamp assembly consists of droplets 3 mm (0.12 in) or larger, or the condensate droplets run down the interior of the lamp, or if standing water is accumulating inside the assembly, these are indications of a seal leak or a clogged vent. There are two cloth patches on the back side of the lamp assembly. The blue patch is the Park/Turn lamp vent, while the grey rectangular patch is the head lamp vent. Both patches should be unobstructed as they may become inoperative if caked with dirt. If the patches are clean and the lamp assembly contains water as described above, the assembly should be replaced. Refer to the Lighting Systems sub-section of the Service Information (SI Document ID #745403) for replacement procedures.
