Leaking Window - Roof support seal to A-Pillar seal

Hi

I realise this is an old article but I am surprised that no body mentioned the second drain tube in the door frames at the front of the car.

The suggested problem in picture 1 should not be an issue if the window closes up hard against the window seals.

However picture four and five shows the drainage channel that runs across and under the front edge of the roof and drops water into a rubber seal channel that is in the door frame and drops the water into the door jam.If that second channel is blocked (and it is a second channel, not the same as the A pillar drainage hose that takes the water out of the roof arm channels) then the water coming out of the cross roof drainage channel is going to overflow into the car.

Also as regards the main roof arm drainage channel and the drainage hose in the A pillar. Even when the drainage hose going down inside the A pillar is clear and fully operational you can still get water flowing into the car (at the front of the roof arm) if dirt, a small leaf or any foreign object obstructs the hard plastic drainage pipe connector between the roof arm (channel) and the start of the drainage hose in the A pillar. I park under a honey locust tree and I have seen its very small leaves get into my roof drainage systems. I recommend periodic cleaning of the drainage channels in the roof arms to ensure nothing will prevent water draining out of the system as it should.
