The windshield wiper on my passenger side of my 1978 f250 has never worked from the time I bought it. What could be the cause of this? I dont think its The wiper motor cause the driver side works perfectly at both speeds.

Same parts: 1973/79 F100/350 & 1978/79 Bronco.
D9TZ-17566-A .. Right Arm & Pivot and D9TZ-17567-A .. Left Wiper Arm & Pivot connect to the stud of the wiper motor output arm (C7TZ-17A436-A) with a clip (C5ZZ-17531-B).
The left arm connects first, then the right arm. If the clip was missing or had broken, neither side would work. I suspect the pivot of the right wiper arm has stripped.
