I have a 1997 Legacy Limited Wagon and last spring I noticed some water coming out under the glove box. I went to a windsheild repair place and they said it was definitely the windsheild. I have had it replaced 2 times now and have brought the car to 2 dealerships and another repair place and the problem persists. Has anyone had any similar experiences and if so, do you happen to know what the problem is and how to remedy it? Thanks in advance for any help.
