Astr Sri 60 plate (LEAK REAR FOOTWELL

[Parv]

Hi all can anyone help me I have noticed my passenger side rear footwell is wet when it rains I can not see where the water is leaking from as the door seals seem fine

It's probably leaking from the base of the windscreen.

Best diagnostic method is to use a smoke generator which if placed in the footwell will show where smoke is leaking through
