I'm wondering if anyone else has seen this. The windshield wiper on my '95 C220 occasionally, like once a week, will spontaneously turn on and sweep the windshield a few times. It is in the intermittent mode when it sweeps. It will stop by itself after a few sweeps or I can stop it buy turning the wiper switch on then off. It appears the either the wiper relay or the wiper switch is going out. Has anyone else seen this? What was the fix?
