- [08\-075\-26 REV. A](/bulletins/11031423.md), 2026-04-22, Service bulletin: ELECTRICAL SYSTEM. Rear Taillamp Condensation Clearing Procedure On occasion, vehicle exterior taillamp assemblies get fogged with a light layer of condensation on the SYMPTOM: inside of the lenses Fig. 1. This may be reported after the lamps have been turned on and brought up to operating temperature, turned off and then rapidly cooled by cold water \(such as rain, or the water from a vehicle wash\). Lens fogging can also occur under certain atmospheric conditions after a vehicle has been parked outside overnight \(i.e. a warm humid day followed by clear cool night\). This will usually clear as atmospheric conditions change to allow the condensation to change back into a vapor. Turning the taillamps on will usually accelerate this process. This bulletin is to communicate the procedure for rear taillamp condensation clearing.
