CHANGING A BULB
Lamp Assembly Condensation
Exterior lamps are vented toaccommodate normal changes in pressure.Condensation can be a natural by-productof this design. When moist air enters thelamp assembly through the vents, there isa possibility that condensation can occurwhen the temperature is cold. Whennormal condensation occurs, a thin film ofmist can form on the interior of the lens.The thin mist eventually clears and exitsthrough the vents during normal operation.Clearing time may take as long as 48 hoursunder dry weather conditions.
Examples of acceptable condensation are:
•Presence of thin mist (no streaks, dripmarks or droplets).
•Fine mist covers less than 50% of thelens.
Examples of unacceptable moisture(usually caused by a lamp water leak) are:
•Water puddle inside the lamp.
•Large water droplets, drip marks orstreaks present on the interior of thelens.
Take your vehicle to a dealer for service ifany of the above conditions ofunacceptable moisture are present.
