I know its a water leak coming from above the heater/AC fresh air intake. Took off the plastic cover in front of the windshield, looked down in the air intake and seen where the fresh air intake tube/horn was located and attempted to smear sealer/silicone around the tube, though I could only get to the side closest to the center. The leak comes down into the heaterbox and onto the blower motor, switching from fresh to recirc., pulling/releasing the glove box down the floor, you can see the stream of water coming down into the heaterbox, directly below the fresh air intake. It is extremely difficult to apply sealer around the tube, so far impossible for me to get to the back side without doing some cutting away of sheetmetal, which I really don't want to do. Started to take off the right fender, but realized no access there either. A friend suggests a liquid sealer he used to seal a leak in one of his airplane fuel tanks, about the consistancy a thick shake, I was considering a spray on sealer, so I'll try one or both. I did manage to slow down the leak but not stop it completely. I went on a search as suggested by Anita and found many different areas where a leak may originate, but I'm pretty sure I've located it, its being able to cure it. So any further ideas will be much appreciated.
