Scott was able to diagnose the problem and showed me that the windshield wiper motor was likely missing teeth from its gears, since it stopped rotating at a certain point (unless you helped it rotate beyond that point, the arm would stay there). To both his & my surprise, the replacement motor has been discontinued and is only built when you special order it, plus it can take up to 2 weeks for the manufacturer to build the motor and possibly a week to ship it. Because we are returning to our home state by that time, I will have to have someone else install it back at my home. I did have him resolve a couple smaller issues and he charged a reasonable rate. If I need a repair on my RV again while I am in the Florida keys, I will not hesitate to call on him. read more
