Hey guys need some guidance here. I own a 99 subaru forester s and the windshield wipers don't work properly. The wipers Park to far both ways so they slam into the edge of the window on both the bottom and side. They do not do this everytime they go up and down but often. And each time they go in their rotation they stop at different points on the windshield. This also only happens when the windshield is wet. If dry the wipers stop normally maybe even a bit not far enough. The more wet the windshield is the more the wipers slap against the edges of the window. Ive already take off the panel to inspect the wiper linkage and cannot find any issues with it. The arms have no issues either and the arms lock into place when bolted on as well. What else could be the issue? Anyone else had similar issues? I'd be very appreciative if someone could share some expertise on this topic and move me in the proper direction to fixing the issue. Thanks
