Serious rain water problem for the last eight months

[Redordead89]

Old thread I know and probs not connected to std common door seal fault but when the drain hole below the wiper motor (driver side!) clogs up with leaves and crud you can easily have at least a litre in there sloshing about and maybe making its way through the bulkhead somewhere and contributing to water dripping in, the hole can be found and cleared easily with a pointy chopstick or similar then use said pointy stick to drag out the leaves etc!
Don't be wearing nice new white nikes when you clear the drain!
