Hello, yeah here in NJ we were under draught for the warmer months. Didn't rain for a while so no leak. I went ahead and replaced the first cab light closest to A pillar cause it looked like it had some moisture in it. I think the design sucks its 1 screw holding it in with a thin screw gasket and clips on the sides with a foam gasket that has aheasive on 1 side. It still leaks. I'm going to wait until spring to remove all the pillar moldings. Lower the frt seats and Lower the headliner. I worked for CJDR for many years and they sublet out their water leaks. I know these outside vendors just yank the headliner down and could care less how it goes back together. It's a strange leak cause sometimes it rains and it won't leak. My carpets are dry, headliner is dry. And it only drips a few drops from grab handle then nothing. It's more annoying cause it happens intermittently. My next thought is maybe it's one of the other cab lights. But it only leaks by drivers grab handle. The satellite antenna is also on that side so not sure if maybe it's that. Gonna attack it myself in spring. Let me know if you come up w something.
