How many days does it take for water accumulated in the chassis to dry under sun exposure?

[StManuel]

It takes about three days of sun exposure for the soundproofing cotton in the chassis to dry completely after being soaked. Check the following factors: whether the sealing strips are aged, cracked, or incomplete, leading to poor sealing and water ingress; whether the waterproof membrane is damaged—inspect the waterproof membrane inside the rear door trim panel and recall if any repairs or modifications were previously done that might have affected the membrane; whether the drainage holes on both sides of the sunroof are clogged—if blocked, rainwater cannot drain through the pipes, causing the water level to rise continuously until it overflows along the headliner and sealing strips, eventually soaking the soundproofing cotton on the floor panel.
