Wiper Comes On With Ignition On or Engine Running

[mharv]

Hi newbie here, car is C Class 200 1995, and the cars wiper single system just swipes intermittently when the stalk is set to 0 and continues every 20 - 30 secs... any ideas.... is the Stalk Control defective... tried new wiper control relay with no luck... fuses are fine...

Can anyone give me the part no to look for without having to dismantle the steering wheel...

Also need guide or diy for removal of steering wheel...

Read through lots of threads but none relevant... great forum by the way

many thanks...

Mike

It is probably the combination sw that is causing the problem.

At the back of the airbag there are two torx screws to remove it. Then to remove the steering wheel there is a 10mm allen bolt.

Dont turn the ignition on when the airbag is disconnected.

BlackC55 can you explain what combination sw is...???

The combination switch is the stalk that you use to set it with

thanks... anyone know the cheapest place to buy one apart from the $tealers ...

only from a breaker or MB

Part No for the part anyone... cheers or do i need to take the steering wheel off??

Best to go to the dealer for this switch as a used one could be faulty also as there are so many functions on the switch.
There are 2 different switches listed for your car , if your quote your VIN you will get the correct one for £80+, not much more than from a breaker.

I believe that the steering wheel and air bag does have to come off

You may also want to check for water in the control unit or relay plate, this is mounted behind the fuse box (drivers side, rear of engine compartment). I had water in mine recently and had problems with the horns and heater, this unit also controls the wipers.

Yes the 202 does have water leaks into the fuse box, there are modified lids for this, as above if you disconnect the stalk that would show if it was faulty

many thanks guys.... for all the info ..
have checked the wiper relay and the area is dry...

Can someone tell me the ft lbs to torque the steering wheel bolt...

 

[mharv]

Television i had taken the wiper relay out and the wiper control would only work above setting 1 with no head light flash or indicators
so is the relay broke or the wiper control stalk... this is my mothers car by the way... bi confused but i do think it is the stalk control
arm?? can you concur

Also do you page of layout for the wiper control arm would appreciate it to see how it connects up....

My wipers flick once when I turn on the ignition because I leave them set to the Automatic rain-sensing setting.
This isn't what you have, is it?

 

[television]

If you do have the rain sensor as MBNuB says the when sweep is correct without any rain, do you have the little blue circle at the top of the screen.

Nissan Primera had same problem

Don't know if this helps but....
My Nissan primera had roughly the same. It would turn on the wipers and then never turn off. After a while it got so that they would stay on even when the wiper hadn't been used. This was a well known Nissan Primera issue.

Resolution was a new wiper motor. I think it works like this...

Relay tells motor to start. motor goes and then tells relay when it's done. Relay then cuts motor power.

But this gets screwed up so that the motor never tells the relay it's in position.

Anyway - that's the nissan primera way of the world and resolution (three of us fixed it with new motors and two of us failed to fix it with new relays) !

btw - I also replaced the wiper stalk but that failed too.

Wiper probs

Hi,

I had the same problem with my 1995 C class (202), the wiper starting up on its own. The fault was slightly conductive dirt in the stalk assembly, the push and turn one on the left of the column. Use a blunt knife to prise off the cap on the end off the stalk, theres a big spring inside so watch it. I then used "servisol" spray to clean out all the black gunge inside. Worked perfectly for me and saved all that airbag hassle. You can buy servisol or any other kind of switch cleaner from RS or Maplins.

A good answer there Peter

 

[mharv]

No it not rain sensing wiper system... just the ordinary...
Peter just to clarify.. you can take the end of the stalk control arm off and spray inside which removes any gunge... ??? if that is the case i will have a look.

Update tried to take the end cap off and used a bit of force on the stalk control and when i tried it later it does not show the symtom any longer..
well weird.. many thanks for all your help and suggestions...

That makes sense. you,ve disturbed the slightly conductive dirt inside the switch. Itl be ok till it falls back into the contacts. The cap I meant was on the end of the stalk, its about 30mm deep, and needs a bit of effort to remove. If you look carefully you,l see a join to the cap. This where you lever it off with the blunt knife !. Once you get into the switch itself (the white bit) its probably not a good idea to strip it further. better to squish it with switch cleaner. If you havnt got any, meths would probably do.
