Just got a 1998 C230. Never had a One-Arm-Wonder-Wiper before. It misses a pie shaped area to the left of the drivers vision area on the return path. It does the passenger side wonderfully. I got a new insert from the dealer and that has reduced the size of the missed area about 50%. Has anyone seen this symptom? Any ideas how to get a clear view, other than to sit in the other seat?
