Hi. I'm new to this forum so please forgive me if I missed a search (couldn't find a search function) , but I am having problems with my 2004 BMW Z4 3.0. (I don't know if it's E85 or not, perhaps someone could enlighten me). Anyway, my wipers are stopping in the middle of the windshield. I had this problem six months ago and the dealer replaced my wiper relay. It has just started malfunctioning again. The wipers stop intermittently and I have to shut the car off to reset them. Recently I had to shut the car off 4 times in a ten mile drive. I have the feeling that it's the wiper relay again, though I don't know if the wipers use one motor. If this post belongs in another forum please politely point that out and I'll move it. Thank you for any help.
