Maseey 6400 roof

[clem dog]

My 6480 leaks an awful amount of water in through the back window when it is raining. Even with the window shut it still drips. Is there any drains or holes that can block and allow this to happen or is just common on all of them?

There’s some wierd drain system on the roof, I took the rear Upper work lights off and the rear plastic Roof cover mine was full of leaves and other organic materials cleared it all out ok now
