Same thing happens on my A-pillar...I havent tracked it down yet thought. Only happens if its POURING. Or if the truck has been sitting in the rain allowing water to run down towards the windshield off the roof.
Do you have a sun roof? If you do then your drain tubes are stopped up. i had that happen to me about a month after i got my truck. just blow them out with an air hose. If not it may be the seal on your windshield.
i had the same problem with my 2007. took her to the dealer wnd was a bad seal on the windshield. they exchanged the widshield under warranty and problem solved....
