Same here. I noticed it dripping from transmission pan. The leak is only outside the car... probably originating from the area where you say the heater valve is located. Can I take that cover off without having to disasemble the wiper?

Thanks for helping out. It's a relief to know that I don't have to tear the dash apart.
