Last Saturday I drove down to the store and back, I guess the trip was about 2 miles. When I got home I was just looking some things over on the car, when I noticed an area on each side of the car was wet and it was dripping. I looked closer and it was fluid from the windshield washer tank. It was running out the hose at the both wipers and would not stop, till I pinched each hose. I never used the wipers on this trip and it wasn't doing it before I left for the store. So what could cause this?
