I have a stupid question. I have been working on a frends 1995 C280, her wipers stopped working. I took it apart today and got it working again, took the motor apart and was filthy in there. Well I put it all back together and when the intermitent wiper is on it stopes with the wiper in the middle of the windshield. Low and high work fine, my question is which side does the wiper go when you turn it off? The driver side or the passenger side?
