I have checked the Relay in the PDC and swapped to a known to have been working BCM and my wipers are still wonky. They have no intermittent at all and when I shut them off they still swipe about 3-4 more times then stop wherever they damn well please. Could there be something wrong with the wiper motor itself. Oh and If I use the auto headlight function and use the wipers the headlights will shut off and come back on at times.
