Not sure of a common problem, but a garden hose and pateince may get you there. Try spraying the area where hood and wipers meet, try not to get the windshield. There may be leaves or debris plugging the drain for the wiper transmission linkage trougth. If nothing happens, next day spray the windshield area, may have a windshield seal leak.

We have a 99 mystique & went thru the same leaking problem. Found out that the cabin air filter seal was bad & had to replace it. After I fixed that, I didnt have anymore problems with it. Good luck.
