I have a problem with my front windshield washer pump. When the windshield wiper setting on the turn signal stalk is put on the highest speed setting, the washer fluid pump will stay on continually. When I place the winshield wiper speed setting to anything slower, it works properly and doesn't turn on the windshiled washer pump. Also, not all the time, but sometimes during start-up, the windshield wiper will come on for a couple seconds, then turn off even though the switch is in the off position. Sometimes I have to cycle the wiper speed switch and then it'll stop. I've already tried replacing the turn signal stalk, but the problem still exists. Looking at the wiper system schematic from my service manual and searching online, I'm thinking maybe it's something with the wiper motor controler, but I'm not sure. Any suggestions on a fix?
