1994-96 Pontiac Grand Prix (Coupes)
Condition
Some of the above listed vehicles may have condensation in the tail lamps or a waterleak in the tail lamps that appears as condensation or water droplets.
The two conditions can be identified as follows:
1.
Condensation appears as a fine mist or white fog, located primarily in the corners of the lamps, after a period of high humidity and typically covers
no more than half of the lens inner surface. These conditions usually clear from the lamp in 2 hours with the lights on or within 24 hours when
parked in a stable, dry atmosphere.
2.
Waterleaks in the lamps appear as a white mist or fog that typically covers more than half of the inner lens, or large drops of water that collect and
run down the inner lens surface.
Cause
May have multiple causes including assembly interference with the body, uneven tail lamp mounting surfaces, insufficient sealing of the tail lamp lens

Correction
Replace the tail lamp. Trim lens and apply additional sealant prior to installation and proper fitting of the lamp to the vehicle.
