Okay, when I run the defroster or a.c. I end up with some water dripping onto the passenger front floor, right under the dash. Is there anything I should try before tearing the dash apart this weekend. Where are all the drains for the heated/a.c. system and front windshield drains? Can I try to blow compressed air to see if anythings plugged up? What all should I be testing? Anyone have this before and have some suggestions? This is not a coolant leak on the floor, which would be the heat exchanger, I fixed this a year and half ago. It is just waterdripping only with the defroster or a.c. Thanks in advance, just trying to save myself some time if possible.
