'94 306 XTDT - the sunroof appears to bee leaking as there is water dripping through the switches. I'm pretty sure it's not coming through the antenna, as the water appers to be coming down the roof liner from the edge of the sunroof itself. The antenna is alos further forward than the swtiches. Is this a common problem? Any ideas how to stop the leak? There is no obvious problem with the seal around the glass itself. Any advice appreciated! Simon
