Technical Windscreen Wipers (stopping / parking problems)

Re: Windscreen wipers sticking??

update, i am yet to check the earthing points, car is booked in tomorrow with electrician.

however i've been having an increased number of problems:

1) sticking wipers
2) passenger headlight cluster
3) heater blower

all of the above work intermittently when i hit a bump or rough surface, which further proves deckchair's assumption of a dodgy earthing point.

all fuses are fine and battery is in tip top condition.

decks, could you please tell me if the passenger light cluster and blower earth through the same point as the wipers?
 
Re: Windscreen wipers sticking??

again deckchair was right as usual :rolleyes: and it was the earthing point C10 that was at fault.

still, the electricians still saw it fit to charge me £60 + VAT, for something i could have easily done myself :bang:

another day, another lesson.
 
Stilo Ecu Problem

Hello there, I would like to ask for help with my Stilo 1,9JTD SW.
Had a problems with crazy windscreen wipers (they worked but speed and switching on and off were without control); headlights (no long and fog lights); rear white lights work only after engine stop (if gear lever has reverse position!). My mechanic find that changing the ecu should solve the problems. Old ecu was looking bad with some moisture and corrosion in contact holes.

After changed ecu Stilo were worked perfectly. I made probe drive today with Connect+ off- needs security code :cool: Heavy rain, windscreen wipers are OK then completely stop to work! Almost kill myself getting car back to mechanic. He is confused, because computer show that all works perfectly. He found power and ground in wire that comes to wiper even they are turned off. Already founded that previous owner tried to connect car alarm or something cutting (wrong maybe?) wire that comes to ecu. Don’t tell me to change mechanic- there aren’t so much quality Fiat services in area. Any ideas what to do now?

Thanks advance,
Nino

Re: Stilo Ecu Problem

Intermittent wiper operation is often caused by congealed grease in the motor preventing an electrical circuit

Power is supplied to the wiper motor all the time, that's normal and it's so that the wipers always have power to return them to the parked position. Your mechanic should know that. Once they reach the parked position then a limit switch stops the circuit but power is still supplied there so be careful if you're working in that area.

The computer cannot detect a fault with the circuit because the wiper park switch opens the circuit - but so does grease on the contacts!

Re: Stilo Ecu Problem

check the black plastic earth block on the inner wing near the battery. Headlight and wiper earths come together there. Probably the reverse light switch is in there as well.
 
Wipers park vertically on screen

Hi

I have a problem with my stilo 1.8 dynamic(2003),the wipers work fine but park almost vertically on the windscreen rather than down on the scuttle:confused:

I have removed the cover from the motor to check for grease contamination on the contacts but all was fine,I cleaned them anyway but the problem still persists.

What should I check next?

My car has the automatic rain sensing wipers.

Any help would be greatly appreciated.
 
Re: Wipers park vertically on screen

The contacts, where you were working, tells it where to chop power and stop the wipers at the parked position. The copper coloured electrical tracks stop and cut off at the park position. There is no conventional park switch like you find on some cars

The tracks need to be clean (this one had way too much grease) and the contacts need to be making good contact so check the spring has enough pressure to keep it in contact with the tracks

There's no controlling electronics in the motor just power in and earth up one end and the position sensing is done just with those 3 contacts and tracks which feed back to the wiper switch just where the wipers are

Do your wipers just sometimes park anywhere but equally sometimes get it right or do they always park mid screen?

Re: Wipers park vertically on screen

Hi!

The wipers always park midscreen,I just removed the motor cover,cleaned off some of the grease,rubbed the contacts with some emery paper and put the cover back on.

The intermittant timer doesn't work though,when I turn the switch to intermittance,the wipers sweep once(parking vertically)then nothing,to make the wipers move again you have to twist the switch again:confused:
 
Re: Wipers park vertically on screen

As there's nothing wrong with the motor, it's just being told wrongly where to park then I'd still go for the park position sensing mechanism of the 3 contacts springs and the sensing track.

Make sure the 3 spring contact pads are clean and bend the springs as necessary to make sure they're making strong enough contact with the tracks

There are 5 contacts in the wiper motor electrical connector. The 2 outside ones are the motor power and earth so you don't need to bother with those. The 3 in the middle are your park position sensor

Re: Wipers park vertically on screen

Bit of lateral thinking on this one.

Might be worth resetting the car's electronics (remove all power for say 30 mins)

Perhaps the body computer has got confused :chin:

Can't do any harm :)
 
Re: Wipers park vertically on screen

I'll have another go at the motor contacts,maybe I was a bit rash putting it all back together,bending the contacts so they have a good positive contact with the wheel is a good idea.

Resetting the electrics might be worth a try too.

Thanks for your help guys(y),I'll try again midweek and report back here with the results.
 
Typical now my wipers are completly gone =( checked the fuse s they all fine not anything working wiper wise trip computer buttom still works on stalk so cant be a faulty stalk any ideas am gonna have another look tommorow
 
What does "completely gone" actually mean?

If they just work when they feel like it and park anywhere on the screen then the answer is in this thread

If you have one wiper doing ok and the other flapping about disconnected then look at Minimad's guide to wiper linkage replacement

You've checked your fuse F43 is ok? (Sorry but some have been known to check the wrong fuse)
Does the rear wiper work?
The front wiper doesn't work on any switch position?
Do the front washers work?
Did the front wipers park properly as normal?
Do you have rain sensitive wipers?
Did they start working intermittently first then go dead or is it suddenly nothing?

Upon starting the engine they work but then 1 min later they dont work , so i am possibly thinking that it may be down to a bad connection or something
 
Now that makes a big difference if they start and then just stop, especially if they just stop anywhere and don't park. If so then read this thread from the start :)

The surplus grease in the motor congeals, especially when it's cold and is a great insulator so there's the poor contact. Just wipe it out leaving just a small trace of grease is all that's needed then.

If you're going in there then make sure the 3 spring contacts are actually making contact as that can also cause problems

But that's quite a job just getting access to the wiper motor so it's also worth checking out the wiper motor earth C10 first to make sure your problem isn't there and that power is being delivered to the wiper motor from the column switch
earth point C10 2.JPG
My C10 is under the windscreen washer bottle, shown disconnected here but you may not need to do that. With C10 still connected, ignition on and wipers selected simply put a multimeter set to voltage, one lead on the metal tab of earth C10 (not the securing bolt) and battery earth. You're looking for near 0 volts of course. Any voltage is bad news and shows a bad earth.Mine was electrically ok but it looked a bit tarnished so I disconnected and cleaned it up before refitting. If yours is ok then you do not need to even remove/disconnect it

(they dont stop in mid air they do go into the park part but they dont move after)

Wow! That's a cracker. So they work, they park and then work no more. Ha!:)

Do they work and just shut themselves off at the park position whilst the wiper switch is still in the ON position? Or do they work fine the first time until you shut them off and then they park and work no more?

Could be anything, switch, park sensing mechanism, grease on the contacts, poor contacts spring force, bad earth at the switch

If it's any help in understanding how they work, it's very different from older style wiper motors with a park switch. There's no park switch as such. There's a + and - feed to the motor and all the timings and logic and done by a control unit in the wiper switch itself. It finds out where the wipers are from those 3 contacts and that odd Viking jewellery shaped bronze coloured cutout using logic. Sort of "contact here, no contact there so wipers must be at point A. Contact here AND contact there so wipers must be at point B" Lovely logic

All just great until you lose contact

I'd do some investigation on "Is there power output from the wiper switch" before getting to grips with that scuttle panel
Slow speed power is pin 8 at connector A on the wiper switch
Fast speed is pin 9 at the same connector

i think we tried just about everything belive it to be something with the computer and the stalk aparently luckly there is a new fiat alfa hyundai specialist opened up near by and have got my self booked in with him there so hopefully all goes well =) hahaha thanks for your help deckchair
