Bloody MB once again using the "lowest bidder."

If it is the lowest bidder then how come it costs 800.00 ?!!

Would not using the wiper much extend its life? My car I dont take out in poor weather including rain so the wiper is barely to never used.

I will open it up when the weather gets warmer and grease the bars.

SWF was the lowest bidder BUT sounds like local dealer may be the thief!
MB suggested list as of 18JAN06 is $570...at that price they make $200 profit!

MB part number is 202-820-07-07..... Check here for price.!.

Not in Canada. MB dealer list here is about $915, but the part can be found for around $800. Mine is skipping and I'll be getting poor for the love a wiper soon. I'd love to buy from Fastlane, but they no longer ship to Canada.

Offhand, does anyone know if that part is updated/improved? Though I guess it makes little difference, since I got eight years out of the first one. But, nice to know they at least took the effort to make something better.

This is the kinda stuff that drives you nuts about Mercedes. I've never owned another car that had it's wiper(s) break. Of course, instead of using a "normal" wiper system that just works, and does it forever, they had to invent the moronoic mono-wiper with it's monkey-motion system that not only streaks the windscreen, but can't clear monsoon-rain like most dual-wiper systems can.

Then, of course, when the super-complicated POS assembly breaks, you have to fork over major dough to replace it, instead of making it repairable.

Same part.......

My earlier post is misleading because i am talking about the wiper motor, not the wiper pivot assembly. Sorry for misleading anyone. In fact, it is true that the pivot assembly is a lot more expensive than the wiper motor. The wiper motor for my 1998 C230 is part number 202 820 04 08, retail approx. 250$ and the pivot is what M.B.Doc is stating. The rest of my post applies

My problem was the plastic gear in the gear box attached to the wiper motor. You can see that gear by taking a little cover off with a torx bit.

Allrighty, all you W202 owners had get serious about maintaining your wiper assembly if you're going to extend it's life. My tech has seen the "10:00 skipping" problem caused by both the motor/gear failure and the wiper guide assembly failure. Mine has just begun to skip, so I headed down there this afternoon.

We took the thing apart and inspected the components, finding everything intact. The horseshoe gear wasn't cracked or broken, but the "guides" were pretty gummy. So, we cleaned it all up and lubed it and put it back together. Presto, no more skipping. Seems I "caught" it in time. In those cases, my tech says he has few folks returning with broken gears as long as they keep up on maintaining the assembly. To tell how often they fail, if we'd found broken/cracked bits, he had all the parts in stock. Several sets actually!

This is for blackmercedes.
Can you give some details on how to remove, disassemble, and clean the wiper assembly. What lube did you use? It sounds like your mechanic has a source for the parts. Where did he get them? Did you also get into the motor gears?

It's pretty simple once you get the outside cover off. He used a grease, not an oil and paid really close attention to the little "rods" that "shoot" out when the arm goes in and out. You have to have the wiper up out of "park" and then get the cover off (simple and easy to see) and then you'll see the guts and it's all kinda laid out in front of you there.

I am goinf to begin paying special attention to this as a maintenance item after getting a shock at the price of the parts involved. As for the parts themselves (which we didn't need for my car, thank goodness) he sources them from Mercedes-Benz. In Canada, some of the larger volume indies can buy from MB Canada, but there is no real savings for me. He knocks 10% of the list price of the parts for regular customers, but that really eats into a thin margin. He needs labour $$ to make a go of it and makes so little on parts.

The real benefit to dealing with an indie that can buy direct is their ability to get stuff from the rebuilding centres. This means a significant savings on big parts like AC compressors, alternators and even engines and transmissions. He can now offer a 722.6 complete replacement with a factory rebuilt (all updates) unit for $3000 including all parts and labour. Sounds like lots, but considering that pretty much any trans for a Japanese car is $2500 for an older four-speed model and labour on top of that, a new 722.6 for $3K is a good deal.

But, it puts that stupid wiper system in perspective. That part is a big percentage of the cost of a new FIVE SPEED AUTOMATIC! Jeez.

So you are saying all you did was pull the cover off? I have done that but all I see are the 2 "slide rods" but I didn't see any horshoe gear. I have lubed those guides a million times with no effect. So you didn't do any actual disassembly at all? I figure I have to pull it all out to get to the actual gears.

All you can do to minimize the risk ( or extend it's life, whatever you prefer ), is keep cleaning & lubing the mechanism on a regular basis.
" Ordinary " wiper mechanisms eventually wear out too, if you keep a vehicle long enough.

No, he pulled the mechanism to access the gears for inspection. I can't remember what tools exactly 'cause my tech just leaned in and in about a minute it was coming out. It didn't take him long at all! In the end, the area he spent the most time with was the two "slide" rods, as the gears were fine. IF the gears are shot, (motor or horseshoe) then lubing the rods won't do a thing.

Of course, pulling the assembly would probably take me two hours, but I haven't done a couple hundred of them! If lubing the rods isn't doing the trick, now you'll have to figure out if you need the motor ($$) or the guide assembly ($$$$$$). Failure of either will cause the skipping you're having.

wiper blades only work on high speed and often will not finish cycle when shut off.
