The windshield wipers on my 96 Tercel are not working good. On slow speed, if it works is real slow. On fast, it works fast on the up stroke and slow on the down stroke . The wiper motor seems to work fine with the wipers off the windshield. I took the vent off below the windshield and sprayed some grease on all the moving wiper mechanism, no good. Checked the wiper blades and windshield and nothing seems abnormal there. Do I need to replace the wiper motor ?
