I have a sunroof - But (for now) water was applied only to edge of windshield. (Not sunroof area) This not to say that the sunroof does not leak - only that water is getting (for now) at the edge of windshield or somewhere lower. Is it possible to check pillar for leak from inside - if I remove the vinyl moulding first? Has anyone had experience with this? I have not (yet) heard of anyone here with the transmitter method. Thanks again.
