NOTICE
Headlamp fogging is a normal occurrence. Headlamp assembly replacement is NOT
necessary to resolve this issue.
1) Normal Moisture / Condensation
Condensation occurring inside the
headlamp/rear combination lamp during or after
a car wash cycle is considered a natural
occurrence. This condition occurs when water
vapor inside the headlamp/rear combination
lamp is exposed to temperature variations.
This condensation is NORMAL and can be
corrected by turning on the headlamps for
approximately 30 minutes with the engine
running. Repair or replacement is NOT
REQUIRED.

2) Water Leak
If water is collecting at the bottom of the
headlamp assembly or the condensation
remains after the headlamps have been on for
30 minutes or more, there may be a water leak
in the assembly. The leak may be caused by a
poor seal between the headlamp housing and
lens, cracks in the headlamp assembly, or poor
fitment.
The condition should be diagnosed and repaired
as necessary.
