Basically take out the a-pillar trim, lower the ceiling piece a bit. pop off one of the tubes, blow some air through there somehow. compressed air or whatever. pour some water into the tube to make sure its draining right, then zip-tie them back on, or youll be doing this again:\
once you get to where you can see the tubes, usually you can see which one is plugged or popped off very easily. since your up there, dont just fix the 1 with the problem, zip-tie em ALL on.
