Hey gang,

My 2004.5 (VIN split) C230K Sport Coupepassenger wiper keeps missing a spot in the middle of the window. Is there any way we can adjust the arm without the tecnical expertise of a Mercedes Tech with tools?? The blades have been replaced same S%#T. Thanks

 

Do you mean it's arching up over a spot, or that the wipe pattern isn't completing?
If it's blade hump (er, so-to-speak), grab a set of replacement blade holders- try switching to the frameless models made by Trico, Rain-X and the like.
If it's a wipe pattern problem, you may need to lube the goomahoochie mechanism:

Thanks Defiant, the Blades are the newer Aero with the spoiler on them. The wiper appears to wipe fine but obviously isn't making solid contact in one spot in center. These are frameless blades consisting of an arch only. This is what the w203 has now. A tech told me the pressure points should/could be adjusted but you need "special tools" (as usual).[:@]

 

Pf. Techs. I liked it better when we were grease monkeys. Well, what is it, a ten-dollar bet? Try bending the little beggar. If it breaks, that was too far.
You might try a really thorough screen cleaning, too.
