Suzuki Esteem water accumulation on driver's side floorboard after heavy rains, possible gap sealing needed on Suzuki Esteem

Some Suzuki Esteem owners report experiencing water accumulation on the driver's side floorboard after heavy rains due to several potential issues. These include clogged sunroof drains, which can prevent proper drainage and allow water to enter the vehicle. Additionally, blockages in the AC evaporator may lead to pooling water on the driver's side. A leaking windscreen is another common source of water intrusion during heavy rain. Owners may also find rusted out welds that create openings for water seepage, as well as clogged drain vents that contribute to the problem. In older models, heater core leaks can result in water leaking onto the floor during rainy conditions. Furthermore, damaged window regulators can allow water to leak into the driver's side, emphasizing the importance of proper maintenance. Addressing these issues promptly through inspection and repairs can help resolve the water accumulation problem effectively.
