Ford Taurus water leak into trunk and front floorboard possibly from light seal failure on Ford Taurus

Some Ford Taurus owners report experiencing water leaks entering the trunk and front floorboard, often attributed to potential light seal failures. Common areas identified for these leaks include the roof seams and rear window, where water can seep through welded metal intersections with drainage holes. Additionally, during heavy rain, water may overflow rubber caps on the roof, leading to trunk leaks; applying silicone caulk to these caps can mitigate the issue. The cowl and filter tray are also known leak sources, and replacing or resealing them, along with installing a rain hat extension, can help prevent water intrusion. Clogged engine drain grommets are another concern, as they can allow water to enter the cabin; ensuring these grommets are clear is vital. Lastly, inspecting the cowl vent screen beneath the windshield wiper is crucial, as water or corrosion in this area may necessitate the replacement of components like the blower motor and resistor. Addressing these issues promptly can help Ford Taurus owners effectively manage and resolve water leak problems.
