Thanks for your replys.
I know it is not electrical as I can hear the motor operate when I trigger a single swipe. The link between the two wiper arms is intact because I can move both arms manually by moving one or the other. When the arms are in the rest position and I trigger the motor, the arms will move up about 2 inches and stop. I am assuming from this that there is a disconnect between the motor assembly and the wiper arms. The diagram I was able to get from Coventry West was of limited help.
I’m concerned how to get the cover off without breaking it and was hoping someone had fixed this before and could tell me “it’s probably this rivet and you can fix it with a bolt”. I was also hoping someone could direct me to a source of service bulletins for this.
