Wiper Arm hard to Pull Back, weird hinge

I'm having a hard time pulling back my wiper blade on my 2002 e320. Manual shows that it should pull back like any car. However, when I try it, it feels like I am really fighting the springs in the arm and would have to use a good chunk of force. So far, I've just pulled it a quarter of the way and carefully turn the blade over while holding the arm up to look at it. It's quite a chore and not as easy as my toyotas. Maybe I'm just being too ginger.

Also, I notice there is this little square shaped hinge between the two springs under the arm that just moves up or down when I move the blade out of it's way. Any clue what this is or what position it should be in? I hope I didn't do anything to it.

Hey, 87. YIKES! It is indeed NOT like a Toyota or Honda, it doesn't come to a 90 degree angle to the windshield. The arm only comes up a little bit, just enough to (1) hold it out of the way when you're cleaning the windshield and (2) change the blade. If you pulled it past that quarter you're referring to, that's too far. FWIW, your Benz is different from those cars in many, many other respects as well, please don't approach it in a like manner.

I'm not sure about the hinge you're referring to, it may be the mechanism that moves the blade up and down as it sweeps left to right.

Did you damage it? Only one way to know, spray some water on the windshield and turn it on. If it jumps, skips or is noisy, you'll have to replace it.

Good luck and enjoy the ride,
Whew!! I thought you'd hauled away on it the way you were describing it, glad you didn't. It only comes up a bit, then the click, which holds it barely off the glass. That's normal, so it sounds like you're good to go.

I haven't thought about lubricating that mechanism, maybe some spray silicone would work well in there. Hmmm. That must be one of the items the stealership includes in the $350 "B" Service. [:D]

Take care and enjoy the ride,
