Service
For headlights, the affected lens surface should be clear after approx. 10 minutes of light operation, although the entire surface may not clear.
In cases where larger water droplets have formed on the inside of the lens or significant amount of water has collected at the bottom of a light
assembly:
^ Check for leaking seals, cracks in lenses or assemblies.
DO NOT replace light or lens assemblies unless damage is found. If damage to seals or cracks to lenses or assemblies are found:
^ Follow normal repair procedures for this type of failure (provide a photograph, if possible, with repair documentation for verification).
If no damage is found:
^ Use compressed air (less than 30 PSI ) to blow out the lens.
