My windshield washer fluid ran completely out last week. I filled the reservoir. It seemed to take much longer than usual for it to get through to the tubes to the windshield, but I thought that was because it has been very cold here in the Midwest lately. It kind of sputtered against the windshield and did not blast it like it usually did. I attributed this to the cold as well. A couple of days later I tried it again. Nothing happens. I can't hear the noise either. The reservoir is still full. Is this a job I can do myself and if so, how? If not, how hard/expensive a job is it for a mechanic? Please let me know as we are expecting an inordinate amount of snow tomorrow. Thanks so very much.
