Hi am a little puzzled my wipers had no problems till today they are resting 1/3 up the windscreen even on intermittent but they will travel down to the bottom before coming back across and then resting again way off were they should
any help please?

thank you

could be to much grease where those 2 prongs make contact- post 13 or wiper stalk problem

That's an odd one, sounds like it is 60 degrees out-of-phase if not what flisko has suggested. Does anyone know if the eccentric on the motor is keyed to the shaft? If not, it could have slipped.

i was gona take the wipers off and re set them but i dont know why they jumped in teh first place lol

Don't do this, from the symptoms you describe, it's not the wipers that have slipped on their spindles, I was describing the driving crank slipping on the motor spindle. If you realign the wipers, they'll just crash into the scuttle panel.

Oh ok thanks il wait for a dry day and take motor off

So what you're saying is that the wipers are 1/3 of the way up the screen, and if you put them on intermittent, they will go upwards to vertical, then down to horizontal at the bottom of the screen, then will come back up by 1/3 and stop. If that is the case, then it's very likely that the drive crank has slipped on the motor spindle.

Worst comes to worst, if you find that realignment is not possible, brand new wiper assemblies (including link arms) are £50 delivered from shop4parts with your FiatForum discount code (donated members only).

Dont belive this its jumped back its self so something defo wrong here

Did you go anywhere on a rough road today or potholes that could have knocked/rattled it back to normal?

Interesting, I wonder if it is keyed but slipped back to its original position? Just to eliminate electrical problems, just blast some contact cleaner in and around the motor.

Becareful just taking the wipers off and then back on

If the spindles are in the wrong position because the drive from the motor has slipped

The wipers MAY want to go down further
Jamming the motor = Burn out
Blowing the fuse
Damaging bodywork / glass / car

ALWAYS TEST THE WIPERS RANGE AND MOVEMENT with tipex marks or a paper/card pointer

So that you know 100% Where the wipers STOP and start

I cocked up when i "bodged" my wipers back together due the failed joint issue
The problem was i attached the linkages upside down = Wipers go down then up

Not up then down = Me Very very quickly yanking the wipers off again

You could do - depends if it went a full 360 - would it touch the bonnet....
I think they would do tbh

could you live with massive chunks missing if it catches?

As i dont know your abilities, as a result - i play it safe
I do the same when i've had to re attach washers on a jaguar XF for example

I set the wipers off
To
A - center themselves
B - Ensure there not going on a full swing on anything

The drive is not keyed and will slip if forced as in a frozen screen or trying to use the wipers as a snow plough.
There is a short arm at the back of the gearbox which in rest position should be at 9 o'clock viewed from the front of the car.
Remove the arms. Operate the wipers and let them come to park. Switch them off, remove the key and disconnect the battery. The torque in the wiper drive is enough to guillotine a finger.
Remove the wiper assembly. Loosen the 13mm nut locking the short arm to the drive without allowing the drive spindle to move from the park position. It is unlikely that this will happen as you are working uphill against a fairly large reduction but still get some counterhold on the arm as you unscrew the nut.
Set the arm to 9 o'clock remembering that now you have it out 9 looks like 3. Tighten up nut. Refit and test with the arms off to make sure it's all hunky dory.

Hi took apart today was the motor linkage small arm was ground round so slipping the motor cog itself is plenty of grip on it so just need a small linkage
no big deal just need to find one online

cheers

Here's one place you can get the whole assembly from. Donated FiatForum members also get 10% off (see Member's Offers).

hi thank you the rest is fine dont really need a whole assembly just the small brass linkage but am getting the feeling i wont get this part on its own

Can you take a photo? The only thing in the assembly I'm aware of that is available seperately are the Wipex linkages. Anything else would probably require salvage from a scrap yard.

And probably just as knackered or bodged to make them last longer like mine

And the locals to me - either have weak ones - weleded ones or tapped with a washer type

Its a shame you cant get the plastic bushing thats needed....

Mind you - they are also now failing on bushings in the spindles, as they develop play causing excess slopp

This is one of the reasons I vowed to change the whole assembly if the car had lived long enough. The other is that the Wipex linkages failed too, which leads me to believe that ball-joints themselves weren't true / smooth.
