2002 Discovery NO SUNROOFS. I have a leak when it rains that runs right down the rear view mirror and drips on to the little shelf by the radio. I have re-caulked the front windscreen including lifting the top trim and getting under it. I have caulked the luggage rack I have caulked the alpine window. I have spent countless hours with a garden hose trying the replicate the leak. All to no avail. ANY help would be appreciated. Did I mention there is no sunroof? I thought I would be immune.
