Guide me in testing wipers - Benzworld.org - Mercedes-Benz Discussion Forum

I have a 1972 220d. The wipers simply do not work. No movement at all, no noise, nothing happening with them.

Can someone please guide me through the diagnostic process to determine what is wrong with them?

I would suggest you have the car crushed. It's a diesel.

Fuse ? Motor ? Connection/cables ? Switch ? You'll have to start somewhere.
Get a multimeter and measure the wires.. If power comes into the switch, if it comes into the motor, wiggle all the fuses to see if there's a bad connection...

1st of all disconnect the motor rotation part from the wiper movement liknage. Now ensure that wipers move freely (by hand) & mechanism is not jammed/rusted. Next do as erick says above. You can remove the motor urself (writing the wire grip colurs to facilitate refiting) then take motor to auto electrician for check up in case multimeter shows that current is OK

On my W116 this summer the wiper stopped working suddenly because the field magnet retaining points became corroded. So I cleaned the motor & stuck the magnet to the body with superglue. Just refitted the armature & it was working like new.

& dont be discouraged by negative comments of grobie. Keep asking any questions that come to ur mind we will help u with dignity.

Did that feel good grubby?

Grobie/grubbie isn't being negative, just realistic!

Here's a newcomer to the vintage board who's reaching out for assistance with a specific W114 problem, that has nothing to do with whether or not the car's a diesel and your only advice is to have his vintage Mercedes-Benz crushed.

I don't *get* your warped sense of humor or see what it adds to anyone reading this vintage forum, which includes 220D's, that were ahead of their time, in their day.

Welcome to the community BenzJeff and keep us posted with your progress

<laugh> E430, an experienced sage such as yourself not *getting* my sense of humor doesn't make me lose sleep

By the way, a 220d isn't a W114 - it's aW115.

Benzjeff, you do indeed have a great car with a bulletproof engine, long lasting transmission and rear end, and parts are easy to find. I'm a big fan of the body styles, but not of the engine (very underpowered). I do like the more modern, turbo'ed ones though.

Something I'd suggest you look into is getting onto eBay and finding a repair manual or CD. I found one for mine and I learned a heck of a lot about my car. The older they get, the more difficult it is to find people to work on them - the more info you have, the better informed you are if a repair issue pops up that you can't take care of on your own.

Hats off to Grubeguy! I salute you for the chivalry of writing again to benzjeff with such encouraging words. You see not all of us merc lovers have the same incomes level to keep these old cars. Most of us love these oldies like a pet. And these benzes can cost a lot to restore maintain & run. In some countries diesel fuel costs almost 1/2 the cost of petrol.
