I have a '97 E36 M3, build date 11/96, with approximately 75k miles on the clock. Clean garaged car, no winters and not much rain. Got stuck in a rain storm recently, half an hour into my drive, while doing 70 in the fast lane in traffic, the wipers just stopped mid windshield. Made it to a gas station, rain-xed the window and when I restarted the car the wipers returned to the home position. I tried them again and they worked for a bit then stopped mid windshield again. Again, I cycled the ignition and they returned to home. Since this happened I have replaced the modulator, pulled out and checked the wiper motor (this helped the problem for about two days,) and checked most of the wiring. I believe this to be a wiring problem perhaps a stretched or chaffed wire but I cant seem to find it. Spoke to two other friends with '97s who said their wipers just didn't work anymore. The problem has developed into these symptoms: 1)single wipe- wipers wipe continuously for maybe 10 stokes then stop mid windshield 2)intermittent wipe-wipers wipe continuously on low speed then stop. 3)low wipe-same as 2 4)high wipe-same... Usually they work when I first start the car then they stop soon after.... Does anyone have any experience with this or anything similar? I am currently buying stock in Rain-X but eventually I need a fix... Help if you can, thanks!
