Toyota RAV4 passenger side leaks water during rain, recurring issue after repair on Toyota RAV4

Some Toyota RAV4 owners report experiencing water leaks on the passenger side, particularly during rain, which can persist even after repairs. These leaks may be attributed to common issues such as clogged drains, faulty seals, or problems with the air conditioning system. Additionally, debris like pine needles can block firewall drains, leading to water accumulation on the passenger side floor. Owners have noted that checking for water streaks on windows and visible mold or mildew on interior surfaces can help identify the source of the leak. To address these issues, some owners find that cleaning the AC drain tube and ensuring that cowl drains are free of blockages can help mitigate water pooling. Regular maintenance, such as checking and cleaning the AC evaporator core drain, is also recommended to prevent future leaks. If leaks continue despite these efforts, revisiting the common causes and solutions may be necessary for effective resolution.
