I already cleaned out the debri in the hood latch wells but that wasn't it. With last nights rain, I have a puddle on both sides again. It is dripping onto the hood release latch and in the same area on the passenger side. I tried to get the wiper grills off but the screw covers didn't want to come off and I didn't want to pry too hard and break it. What's the trick to get the grill off?
