Why would water be leaking under seat?

Water leaking under a seat could be due to several reasons, such as a clogged or damaged drainage system, which can cause water to back up and leak into the interior. It might also be a result of a leak from a window, door seal, or sunroof, allowing rainwater or moisture to enter the vehicle. Additionally, condensation from air conditioning systems can accumulate and leak if the drain is blocked. Identifying the exact source is essential for proper repair.
