Hi All

I am in need of some urgent advice please.

The wipers on my stilo 1.2 16v have stopped working yesterday, front and back. The windsreen washers both work okay, so does the computer trip, i tried cleaning the front motor of its grease as recomended on the site here. I have a live feed at loom from the switch, fuse box, (fuse is okay) but there seems to be no live feed at the front motor. Are the two motors linked in any way? I think it could be a wiper relay (cheapest option) where is it located? does anyone have any ideas, or have had the same problem.

Any help would be apreciated. What a great site!!

Normally would jump straight for the fuses and relay with a chain of componets knocked out and relay T12 is common to both front and rear BUT this also feeds your washers and they're ok so it isn't there where your problem lies.

If you have power to the switch but no power at the motor then, logically, it sounds like you have an open circuit in the wiper switch area, either a poor contact at the wiper switch connector or within the switch itself

At the wiper switch connector A
See if you have power in on pin 11
Earth on Pin 7
front wiper slow speed power should be coming out of pin 8
front wiper fast should be on pin 9

If not then there's a switch internal problem

Switch is H5
Front wiper is N15
Front washer pump is N22

Hopefully, your pinout for H5 connector A should be like this


See if you have
Earth on Pin 5 connector C

Pinout for H5 connector C


Worth noting that the washer pump is the same motor for front and back washers, pump polarity direction is just reversed


Also pump earth goes from H5 pin 7 to earth point C10 whereas both wiper motors earth is from H5 pin 5 to earth point C15 CHECK THIS EARTH LINE TOO!

Thanks Deckchair 5, what a fountain of info, i wont be able to check this until the weekend, my electrics are not my good point. If it is the switch how easy is it to change? How much do they cost approx?
I done a front wheel bearing last week, that was a bit tricky but the switch looks more difficult.

Cheers Wicksy

The stalk assembly is £100 or more but they do come up on ebay now and again.

Replacing it means steering wheel and airbag out so I'd advise taking it to a garage if it needs replacing as it's only a 30min job but it could be the last job you ever do if you don't know what you're doing - A lot of people think they know what they're doing and get away with it but the others don't do it twice if you get my drift.

But find out if that IS the problem first as a poor contact there will do the same thing and not cost anything to repair

i had a similar fault, along with other symptoms caused by a faulty earth from the drivers headlight cluster

Hi All

I decided to take to Fiat dealer to see if they could find the fault. They say it's the wiper switch and have quoted (are you all sitting down now) £260 inc vat. Is it really that difficult to change, they say 45mins, with the switch being £150.
I asked how much the hourly charge for labour is- £84 was the reply.

Still with this hot weather i dont need the wipers yet.

Still debating if i should have a go myself.

Any more advice appreciated.

Be sure exactly what part you need, but it is probably this.
http://cgi.ebay.co.uk/FIAT-STILO-INDICATOR-SWITCH_W0QQitemZ320249985518QQihZ011QQcategoryZ10382QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
Buy this and DIY if you are competent at pulling things apart and putting them back together with no bits left over after you have finished.

It is quite likely they have got the diagnosis wrong though.

Have you checked the earth lines from the switch?
You know you have power to the switch as the washers are working. The earth line going to earth C15 is crucial to both front and back wiper motors

See if you can find it as it looks like it's near the battery. Looks like a black match box with, of course black or black/purple wire going in.

Without C15 giving good line to earth then it's no wiper motors

The ebay item switch John mentioned is one with cruise control, if you haven't got cc then you may be able to find an even cheaper one

Here's one without cc
Changing the indicator/wiper switch assembly means steering wheel and air bag out and clock spring securing which is ok if you know what you're doing, life changing hospital experience if you don't


Here's the clock spring retaining pin in red


Once you have the steering wheel off then it's a simple single securing screw to loosen the unit and it's off

I will check this earth out tonight when i get in. I seem to remember having no live feed at the front wiper motor last week, would the bad earth at the front possibly cause this?

Why do these modern cars have to have all this gadetry, i suppose to try and sell more cars, eg "well my cars got Sat TV,DVD,skyTV,Mobile phone,ejector seat,flame thrower etc,etc,etc"

When you try a sell a car in Autotrader in a few years you will need a whole page to advertise.

We like gadgets

The switch supplies the live power to the motor (rather than supplying an earth to the motor like the heater fan circuit) and there is a timing relay for the int wipe and a diode inside the switch so plenty to go wrong there



The earth C10 and C11 depending on whether you're lh or rh drive is also on the hit list which is what BBS had problems with and that's near the front rh headlight apparently

I had a problem with the earth point on the Flitch, left side near the battery. It caused my front wipers to go very slowly and N/S headlamp not to strike, just flicker (Zenon light). Rear wiper was OK though.

Thanks for all your help and info.

I had to bite the bullet and take to Fiat's, not the best £260 iv'e spent but at least i now have wipers.

It was the switch, just my luck :bang:

They also gave me a visual inspection check list (just looking for more work i guess)

All the best Wicksy.

to be honest, as able as i am at times, a job like that i would have taken to fiat to do. I had to get them to find the earth fault causing my wiper problems but cost me nothing

Hi All,
I have read through the thread and found it very helpful. I have a Stilo 1.2; 52 reg with a simmilar sort of problem that started today. The front and rear wipers were fine this morning then stoped working. The front and rear washer is working perfectly fine. I checked the fuse and that was ok. For some reason I left the car for an hour or two and then checked again and the wipers were ok again. Later in the day they stopped.
I have serached through this forum and found very usefull hints and tips, I even used WD40 for the relay fuse box close to the battery and cleaned all the relays and fuses in that location. The wipers started again. But unfortunately now they have stopped working.
I am not sure what else to do? If there are any other connections to check please advise, it will be much appreciated.
Thanks

Hi Guys, I know this is an old thread (And I shouldn't be waking up the dead) but I have tested the voltage at pin 11 but no voltage at all :bang: the ground at pin 7 is poor as well. Now I need to find out what my next step is to the reason why I have no voltage at pin 11.

When I test the 12V at pin 7 to body ground I get the 12v, but I test the Pin 7 to ground at pin 7 I only get 4.4V Max. Bad Ground I believe? Anything I could do to fix any of these other than wire a whole new ground and voltage source?

Also the rear wiper aren't working either but the washer is working.

Pin 11 does not provide a voltage source but instead is the pin to move the wipers at fast speed. When Pin 11 Received a high voltage, then the wipers moves. Now, the voltage source on the plug is situated at pin 7.

Therefore, I'm not too sure which pin is meant to be the ground but seems to me that the problem comes from the stalk itself.

Below is what I believe is pin 11 and 7. Correct me if I'm wrong. but seem to me that pin should not have the voltage source and there's the wrong information up there.
