hi again connected new coloum switch still not working any ideas where earth points are for coloum and is there any other relays other than in drivers footwell fuse box

Technical wiper fault
Ok now the more information you can supply the better. The timing relay in the circuit is the one in the wiper switch assembly and that's only there to provide a means for the timer in the intermittent wipe etc.
There is a 30amp power relay for the wipers (T12) which also has an earth at C15A so once you find C15A and C15B then that may cure all
Did you hear/ feel the wiper switch relay clicking in and out when it was playing up. Was the relay still dropping out mid stroke and causing the wiper to stop functioning?
Here's the wiring diag again to save you clicking over to page 1 all the time
OK now if you look at wiring diag you see the earth line for the switch is C15B, a black wire coming out of pin 5 at the wiper connector and going to pin 2 at the earth point (C15A and C15B are at the same earth point in the diag below). I can't tell you exactly where that is as I've never needed to find it but look in the picture below for C15A and C15B.
BUTTTTT for the switch relay to be dropping out then I'd check out the relay earth line. This is shown as pin 7 at the wiper switch, again a black wire (shown as N for Negro) going to C10 pin 15. Now the wiring diagram is for left hand drive you'll notice so the earth point could equally by C11 over on the other side but the same relative position.

my wipers always bang eachother when they go down-normal?!?!?!?!? xx
Deckchair...I assume by the pictures you have posted up that you have a stilo elearn disc...why dont use use wiper fault chart? (in fault diagnosis)
The Italians seems to start the wrong end for me
Something to do with Mussolini I think
They start at the power side of things rather than working back from the earth whereas, as you know, so many faults are caused by bad earths
They never have anything that's intermittent in their fault charts- they're the most common and irritating ones.
"Hey make your mind up uh? It goes- it doesn't go- when it doesn't go - you bring it in uh?"

Right from the diagram you have posted pin 6 (think it's 6?...I need glasses!) from switch to pin 3 on motor is the earth signal wire from the motor cam..i.e. park signal posistion,the cam operating microswitch inside motor at end of one complete cycle/wipe.
Easiest way to check would be using power probe (or normal test light to batt +) to check that a neg is being produced after each cycle & to check this wire is earth when wipers switch off...if not needs a motor,which I suspect.This signal is obviously vital to park the cycle & tell the switch where the wipers are currently posistioned.

Tricky isn't it. But the fact Keith is hearing the relay (which one I don't know) clicking in and out and the power to the wiper motor is going on and off sounds like the fault is prior to the wiper switch.
hi guys when the power comes/goes their is a definate clicking i.e relay sound. coming from coloum switch
Have you checked that earth line to C10 or possibly C11? That's the earth for the column switch relay. C10 is situated between the battery and the headlight and C11 is in the same relative position on the other side

Hi,
I've got the exact same fault on my 2002 1.6 active Stilo, it's really annoying me now, anyone found a cure for this fault, can hear the clicking noise, wipers come on when i start the car when they are switched off.
They don't stop in the correct position either, i do a lot of motorway driving and this fault is dangerous at this time of year, after about 10 to 15 minutes of driving they seem to correct themselves BUT only if it is raining, could this be a sensor. :bang:
I also have a problem with the engine warning light comming on intermittent at first but now its on all the time, amber and there is a problem with the idle speed dropping when car is stopped occasionally cutting out. This happened to me before and was fixed under warranty but warranty has expired, any ideas
I think once it is fixed i will be getting rid of it, also had probs with the central locking, had a nightmare of a time trying to fit a new headlight bulb had to remove the battery and the plastic housing to get my hand in to change the bulb, shocking design. Oh and the sun visor keeps falling off.

"wipers come on when i start the car when they are switched off.

Now that IS the wiper motor park switch

It's usually a plastic switch actually in/on the wiper motor. Can't be specific about the Stilo as I haven't needed to touch the wipers. Often it's part and parcel of the electrical connectors on the wiper motor body.
It's a simple microswitch that detects when the wipers are in the parked position by a simple one lobe cam and chops the power. The reason your wipers start even when the the switch is in the off position is that this switch hasn't chopped the power (or your wipers aren't parked)
On cars that I've rplaced the switch then you simply disconnect it, detach it from the the wiper motor and replace it
I would check out the electrical connector on the wiper motor itself for poor contact first as that will cause the same symptoms
Here's a piccy of the wiper motor and connector. The connector may even be the park switch as it often is

hi you got any pics exactly where the earth points i.e C10 C11 thanks iv looked but not noticable
Looks like they're just behind the headlights attached to the inner wings. Is that where you looked?
yes there dosnt seem to be anything there?:bang: :bang: :bang:
Bit dark for me to have a look
What have you checked so far? Is it still doing the same? You turn the igntion on and the wipers sometimes go for one flick wipe and park? You turn off the wipers and they just stop wherever they are but sometimes park properly?

tryd relay ,wiper motor,coloum switch, when you select any position on coloum wipers will work from where they have parked which could be anywhere across screen then they will work for 5 to 10 secs then switch off then wait for 5 to 10 secs they will start up again and thats it
Earth point C10 is right next to the bonnet stay passenger side.
Big jobby. 3" X 1" connected to the wing
Take off the battery cover, follow the line of the fuses, there it is -attached to the inner wing. Small plastic spring clips to press in to release. Undo the securing nut and make sure you have really good clean contatct to earth
Do the wipers run slow? Struggle?
Do they actually move fast on the flick or fast setting?
If they're s running slow/struggling that would point more to earth or bad connection problems
What do you mean by you've "tried the relay" "tried the motor" What did you try?
Have you replaced the relay? Replaced the fuse?
I know you've substituted the switch

hi when wipers do work they work at normal speeds at which is selected fast slow int took relay out of wifes stilo and still the same took block connecter off wiper motor and put tester on the block put wipers on and theres intermittent power showing on meter at all settings on stalk.when ign is switched on and wipers arnt parked they will start at turn of key if parked they stay put till stalk moved rear wipers always work perfect
