[Audi A3/S3] Wiper arm replacement

Hi people

my '98 A3 has suddenly seized up its front wipers... Fronm my own assumptions and also reading the forum it would seem it's to do with the motor or linkage that has some defect.

Now, I have a manual for this kind of repair, but can't seem to actually get the wiper arms off their screw/spindle thingy. The manual says to "rock" the arm until it eases off, but no luck with that approach. Has anyone had this problem before - and if so, how did you solve it?

Am I maybe missing something else here? Any tips would be much appreciated.

Cheers

Lev

PS I am in Scotland and the rain is never far off - please help!!

Sorry, should have mentioned that. I had removed the nut and pulled, but it wouldn't come loose. Just wondered if it was just seized/rusty or if I was actually missing something that was keeping the arm from coming off...

Have you ever opened the actual wiper motor? Is it complicated? Is there a place online where I could order a replacement, or does Halford's do that kinda thing?

Lots of questions, I know, but only just got the A3, cheers!

It's not actually the wipers that are the problem, but the motor (or linkage). The reason I asked about the arm replacement is to find out whether I was missing something, as they weren't coming off. Obviously they need to come off in order to get to the motor and linkage of the wipers.

I put some WD40 on it yesterday and will check later if that has done the trick in loosening them. Thanks for all the replies and offer of wiper arms!

cheers

Just to give you all an update - in case you need to do this yourself - I have finally managed to get the wiper arms off (with a lot of wd40 and 'rocking' - carefull never fully twist the arms off as that will damage the splines irreversably).

To see why the arms were moving so slowly and eventually stopping entirely, I then removed the splash cover. Tip: start on the right as the radiator side comes off more easily. The cover is clipped in just underneath the windscreen, so once you pull it loose the rest should come off quite easily.

I then removed the linkage and motor unit of the wipers (3 nuts to be removed - easy) and after removing the motor unit from the linkage (4 nuts - easy) was able to see if it was the linkage or the motor that was causing the problem. The motor (reconnected on its own) worked fine, while the linkage seemed seized up. So I ordered a new linkage from Audi (approx 30 pounds plus VAT) and will install everything tomorrow.

Will keep you posted if that fixes it (it better!!). Just a last tip: Make sure you look out for any washers, nuts etc. They have a tendency to slip out of your hand and into the engine compartment (yes - it happened to me blush.gif ).

Right -- I got the linkage from Audi, but they only supply the main bit of the linkage (the part that holds the turning spline for the wiper arm) and not the “connecting rods” that allow the whole linkage to fit together and move simultaneously.

Here is a short list of the next steps, with a more detailed explanation after:

1) Take note of the linkage alignment

2) Take off connecting rods

3) Put connecting rods onto new linkage

4) Reinstall the linkage & motor

In detail:

1) Make sure you take note what the exact alignment of the linkage is, as you will otherwise not get the usual up down movement of your windscreen wiper, but a “down/half up/down” motion. So make sure the linkage is aligned flat.

2) Take the connecting rods off their joints by using a screw driver to lever them off. They are just clipped onto a ball joint and will pop off.

3) Before you clip the rods onto the new linkage, make sure you lube the ball joints on the new linkage. Just clip them back on to the ball joint with help of a hammer.

4) Reattach the motor and reinstall the linkage + motor.

For the other parts just reverse your instructions and reinstall all parts as taken off.

cheers

Lev
