Leaking when it rains? Where in the hell is this water coming from?

Ok great ideas and tips. I finally located the slot hole on the side, sorta hidden under the torsion spring for hood. cant really get any tool into it. So I opened up the body plug (why I never thought of that before?) and put a small brush and began digging out several trays full of junk. Then was able to put in a water sprayer from my hose and spray towrads the drain hole and got it to run clean. Several trays worth of junk on the right side as well. Now I need to test it to see if water is still dripping into the car. Side note, upon inspection of the left side,which is where majority of water is coming, I did see that the antenna wire grommet was away from the panel, so possibly water is running down into the panel, hitting the antenna cable then snaking through the hole and under the dash and dripping. will also try to plug up the grommet better.
