Truck Trend Garage: 1996 Nissan Pathfinder Leaky Sunroof
Expert Advice: Sunroof Leaking
If you can feel the relief of pressure as the tube is cleared or see the debris blow out the lower end of the tube, you might have fixed the leak. If the sunroof tubes look good, remove the interior trim panels in the wet area and run a garden hose consistently over the exterior parts of that section while carefully inspecting the inside for a water entry point. It could be a poor weatherstrip seal, separation at a body seal, or a missing body plug. Remember, when using a sealant to patch a water leak, always apply the sealant from the outside. It's a much stronger fix.
