C220 wiper fault.

[shawkerr]

The wipers on my 2001 C220 cdi will not operate on startup until I reach 5mph, and stop wherever when I stop. I've been told that I need a new wiper motor complete. Any advice please.

Hello and welcome,, what an odd fault to have,, I do not see why it wants a motor though

Sounds like something on the wiper linkage is siezing up and when you get the extra voltage from your alternator they work then when you stop the voltage will drop slightly causing the wipers to stop also.

I think the above is a very good answer,, have a look in the DIY section on how to oil it

Is it a single or double wiper on the 203 Malcolm?

 

[Ultymate]

Answering my own question here it's a double wiper setup, it could be one of the two wheelboxes siezing or part of the linkage betwixt the two. Looks like a fair bit of work to get to

I had a c220 cdi SC, and I believe that is correct operation for the wipers, it's so it doesn't operate on a dry window, especially when you are travelling in a queue.

203 Wipers

Unless I'm missing something, this is the correct operation for these wipers when rain sensors are not fitted. Below approx 5MPH, they drop a 'notch'; i.e. from Inter to Off; from Slow to Inter, etc., and revert to setting when car starts to move.
With rain sensors something similar happens, except that Intermittent becomes almost non-existent. Sometimes I find that its better to press the button for a manual wipe.

Hope this helps.

Thanks for the reply.

Wipers work when vehicle moves above approx 5mph, irrespective of engine revs!!!

Speed Related Operations

There are a number of speed related operations on MBs, to name but three:
wipers, seat-belt warning, auto-locking and maybe more. Hope this helps.

You're right, it does sound like a lot of work.

In normal operation, on starting up the wipers can be operated before the car is in motion, one must be able to see through the windscreen. At the moment the wipers will not operate until approx 5mph is reached. Normal operation when one stops at traffic lights etc, is for the wipers to park after perhaps one sweep, at the moment they stop wherever they the instant the car is stationary!

Thanks, but it occurs irrespective of engine revs!!

It's MPH related - not rev's related, if that helps.

When stationary do the wipers give a single wipe when you press the stalk? If they do it would rule out a linkage problem.
The wipers will not operate if either front door or window is open. Do you routinely open you window at start-up? This function cancels at speeds above ~5mph.
