The Mercedes-Benz S Class has been the worlds top selling luxury sedan ever since its introduction in 1972. Ever since that time, Mercedes has used the S Class as its flagship and industry touchstone, using it as a platform to launch all of its cutting edge technological innovations and features. The W220, which ran from 1999 to 2005, was a marvelous continuation of this tradition. Some owners say that they have problems with their wipers shuttering or jerking across the windshield.
When it rains, you expect that your wipers will work appropriately in order to whisk away all of that excess water. Malfunctioning wipers are a disturbing, annoying, and potentially dangerous issue that some W220 owners experience. Commonly, the report is that the wipers work fine when on their fastest setting, but on the lower settings the wipers shutter and bump across the windshield, making a tremendous racket, and resulting in near impossible driving conditions. Fixing this problem is essential before any bad-weather driving can be considered.
Several possible complications could be the reason behind the malfunctioning windshield wipers. Most noticeably, the wiper itself could me misaligned or misshapen. This can sometimes happen during the replacing of a wiper blade, and it would result in an uneven track across the windshield itself. Another potential cause lies with the wiper motor gear, which tends to wear out over time. If this is the case, you are likely looking at a new gear or motor assembly to replace the worn out part.
Solving this problem is a time consuming project that is often more frustrating than it is successful. Instead of struggling through all the possible options yourself—and potentially worsening the situation at hand—try taking your W220 to a local Mercedes-Benz maintenance expert. A professional such as this will easily be able to narrow down the exact cause of the wiper shuttering and have your car returned to the road and ready for inclement weather of all sorts.
