I have just purchased a 1998 C230. It has 92,000 on it and is in excellent condition with one exception. The windshield wiper will not go on, I've checked the fuses and they are ok. I do alot of repairs and replacement on all my cars and vans, boat, I would like to check and or replace windshield problem if possaible. Anybody out there have any suggestions. I hope so. Thanks
