Got in the wifee's 94' GT the other day and the windshield wipers were on from the day before and when I turned the switch off, they stayed on. I turned the switch ti high and it went on high. Turned it back to low and it went to low. Turned it to off and it still stayed on. W.T.F.??? So, I replaced the switch with a brand new Motorcraft assembly from Dallas Mustang, and it still does the same thing. Anyone ever had this happen to them? Could it be a short in the windshield wiper motor itself? Seems like it would quit working, not stay on! Any input would be greatly appreciated.
