Usually this sort of leakage at the rear hatch of the coupees is caused by a blocked drainage pipe. The groove around the rear window opening goes into a vertical pipe that is laminated in the back of the car. You can see it on the inside.It empties itself just above the rear bumper. Usually it is full of leaves. If a previous owner cut a hole in the groove for the lock of the rear window, rain water will find its way into the interior via this hole. If this is the case:
a) remove the rear bumper and use a screwdriver o.e. and lots of water to clear the blockage of the pipe.
b) shorten the locking lever of the rear hatch, install a L-shaped bracket for the catch and close the previous used locking hole.
