The A pillar is the pillar at the left and right of the windshield. In a car, the A pillar is in the front, and each pillar is labeled alphabetically after that. So if you have a pillar between front and rear doors, that is the B pillar, and the one at the back glass is usually the C pillar. On wagons and SUVs, you can have a C behind the rear doors, then the back glass is the D pillar.
Yes, it had a leak, as does the one behind me in the picture.

When you are sitting in the driver's seat, my water was coming out the grab handle bolts near the windshield.
My truck just went to the shop yesterday, so it isn't fixed yet. This is the second time it has been to Ford. This time code P245A - EGR cooler bypass control circuit. Don't ask me, they are covering it under warranty. I've also had a problem with the engine fan clutch not engaging properly, which caused an overheat condition once.
