SuiteSuccess Posted July 26, 2019 Report Share Posted July 26, 2019 I finally found a glass shop willing to track down a persistent water leak that would drip down the drivers side curtain channel after a heavy rain. I had tried hosing and other means to find it and couldn’t. Truck is Volvo 780 with skylight which I and other forum member thought might be the source. Turns out the source was the two channels on the roof that I thought (and was told) were just dimples in a one piece roof. Apparently those may be rolled seams of three separate panels. Also apparently these seams require periodic resealing with polyurethane. I hadn’t done that and I had cracks and even couple of holes that were repaired. Learning something new every day. Might check yours if older Volvo.

Parrformance Posted July 26, 2019 Report Share Posted July 26, 2019 May also want to seal these same seams under the fairings at the back of the cab. I resealed the seams and a year later a new leak began, I traced it to the driver side fairing below the joint where it meets the upper fairing. Only leaked during very heavy Florida tropical downpours.

SuiteSuccess Posted July 29, 2019 Author Report Share Posted July 29, 2019 It’s the two grooves on either side of the sun roof.
