Have had a bit water coming in front footwell, stopped with cheap easy repair.
Tools: Spirit or other cleaner, contact adhesive & a cloth
Photos speak for them self
Lifted loose seal - cleaned - applied glue - wait - fix seal - pressure on with cloth, door closed.
1 photo didn't work, was one showing both seal and frame with glue drying for required time (15-20 minutes) before fixing together, next photo is the one with the cloth in between door and seal for added pressure for good few hours.
