Hi,my name is mike and I will assist you with your question.
Does the vehicle have a sunroof?
Customer: replied 3 years ago.

yes

Expert:  Mike Kelly replied 3 years ago.
Ok the most common reason for this to happen is the drains at the corners of the sunroof housing that lead down through the side interior molding have come loose from the tube allowing the water to escape inside of the interior of the vehicle.As a first step the drains and tubes need to be checked.
Customer: replied 3 years ago.

drains are all good ?

Expert:  Mike Kelly replied 3 years ago.
Ok if the drains and the tubes are all good. The boot seal and the door seals need to be checked as a next step.
