I was wondering if anyone knew how to replace the wiper blade for the headlight on the c43? And if there was a website or part number that I can buy from the dealer also

If I'm not mistaken, you need to change the blade and arm. I did on both sides. Its NOT a cheap solution!

The arm is okay but I thought of changing the blade but If it's to expensive I'll just leave it as it is.

Just be careful that the blade is not worn cause it could damage the glass...

The rubber on the blade is still kind of soft. I also noticed that the headlight blade arm sticks half way on the headlight. When I turn on the windshield wiper blade. Is this a common problem? I'll try to take a picture.

Wow I also noticed today that my windshield wiper blade wash system is not working. Usually water comes out from the little nozzles on the hood when I press the wiper blade wash function. I checked the windshield reservoir and filled it with water but still water won't spray out? Could the nozzles be dirty or clogged? Or the pump might be going bad?
