Hi Erin,

Others will know more but from past posts the two most often problem causing this seemed to be a bad  antenna seal or a lack of a seal on the windshield gasket.  These are more likely if the water comes when van is just sitting.  If more when driving then I think there could be something else I’ve read about the headlight area.  But usually it is one of the former.
