My 21 3500 laramie have a lot water leak again from driver side . Last time its was leak from third brake light i put marine seal and zip tape on there and its no more leak. But the leak come out again yesterday. I check third brake light its dry and clean. And i also check the clearance light no leak from there. Its a lot water leak only 20 min rain when i drive the truck i can hear there is lot water on the cab . Leak only appear when i park the truck down hill.Anyone have idea where leak come from? Maybe the sunroof?
