Thanks guys the vent panel I will check also,
but the water is coming in from the top in the front EG above the sunvisor thru the
panel that runs along the top off windscreen -internal trim-(Rear View Mirror in the middle, that one)
But Im not sure if its the sunroof or the windsheild, need to remove panel first and run water to see, will post when I find out.
The wiper vent panels will get a going over also.
Re the rear Seal around the whole rear tailgate this is new , not sure how to tighten door closure to give more pressure contact between door and seal?

If you have suggestion this would help . The actual glass mounting rubber seems fine though
Any way thanks and cheers from BB(Steve)
