Moisture or condensation under cap
Bronco has a lift
which is higher in back that front providing a slight slant which would prevent a leak at body frame from running aft towards back glass. Cap is faded and dull. This is a 1989 full size Bronco and am not sure if there was any recalls
Moisture appears after rain or warm to cold nights. Covered with a tarp before the last rain and checked later and there was no moisture or condensation. I am out of ideas
