The diode in the wiper motor is part of the reversing - the motor runs one way, hits a switch, polarity flips and it runs the other way.
If both headlight wipers are oscillating back and forth - I think the diode would be ok. If one was stuck, I'd suspect a shorted diode, given that the windshield wipers run.
The 2 wiper motors and the headlight washer pump could be in play for this behavior. Disconnect each in turn.
