Classification: Reference: EL03-030d Date: NTB03-074d August 8, 2008 EXTERIOR LAMP FOGGING This bulletin has been amended to apply to all current production models. Please discard all earlier versions. APPLIED VEHICLES: 2001-2009 Nissan, All Models SERVICE INFORMATION: Occasionally customers may notice water 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 this 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. Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle. 1/3 Fog may temporarily form inside the lens of the exterior lights based on environmental conditions or sudden temperature changes, such as a car wash, may cause. This is normal. See Figure 1. Head lamp Grille "Cloudy" condensation (fog) Lens area TP030533 Figure 1: Example of normal condensation, ok NOTE: This condensation can appear anywhere on the outer lens, typically at its coldest location. Head lamp Grille Water droplets or pools Lens area TP030534 Figure 2: Condition may not be normal If the moisture trickles, drips, or pools, it may not be considered normal and the lamp assembly may have a water leak path. See Figure 2 for an example. If large drops of water collect inside the lens, refer to the flow chart on page 3 to find the next step. 2/3 NTB03-074d SERVICE PROCEDURE Should a customer note water in a lamp assembly, please use the following flow chart to determine if the condition is normal or requires lamp replacement. NO Visual inspection-Does the lamp show any puddles, runs on lens, or large (larger than 3 mm diameter) droplets of water? YES Pull vehicle into service bay. Turn on low beam headlamps and hazard flashers. Monitor the condensation in the lamps for 10 to 20 minutes. Is condensation area on lens clearing? NO YES DO NOT replace lamp assembly Inform the customer the following: • All lamps allow some moisture (water vapor) inside through vents which prevent physical damage due to pressure buildup when lamps are turned on. • Certain weather conditions will cause water vapor to become visible on lens. • Condensation will clear on its own as the environmental conditions change. • Warming the lamp will decrease the time required to clear. *Replace lamp assembly *Refer to the Electronic Service Manual for lamp assy. replacement. *Refer to the Warranty FRT Manual for claims coding. *Warranty part return of the lamp may be requested. 3/3 NTB03-074d
