Tail Light problems of the 1998 Mercury Mystique

We purchased a Ford Mercury vehicle, used, and found it had no tail lights. We identified a recall notice. The dealer refused to fix the problem because they said the recall work had already been done. We took the car to another mechanic and found it had original equipment, with the defect still present. Ford refused to honor the recall, citing that it was our responsibility to fix the problem because the work had been done. The dealer refused to check to make sure the problem had been fixed. The broken part was original equipment and had the cited problem in the recall notice.

Water accumulates in the rear right light fixture by the trunk causing it to leak from the fixture when the trunk is open or if the vehicle is moving.

There is water in the tail lights. Dealer has been notified. Please provide further details.

When ever it has been raining or there is heavy dew outside, rain or moisture would enter the rear lights. Have taken to dealership several times and was informed each time it was the factory sealant that had failed. The sealant can not be resealed. Would need to replace the entire rear lighting system.

After rain tail light fill ed up with water and cracked lens. Please provide further information.
