Our 87 760 will dribble rain water onto the drivers side floor mat. I have seen it come down a couple of wires that are up above in the far left corner. I have gooped up the windsheild rubber all the way across the front. I have gooped up the rubber boots under the hood where wire bundles come out of the drivers side engine fire wall. It still lets in water. Is there a drain hole somewheres that is clogged? Were out of ideas.

Thanks in advance
