Wipers stopping mid wipe

[AlphaPapa]

Hi Gents, I am really hoping someone can help me out with this one as its become quite dangerous IMO.

I can be going for 10 minutes sometime 30 minutes or more and then all of a sudden my wipers will freeze mid wipe leaving me effectivley blind. 9 times out of 10 i have to pull over and switch the engine off and on again a few times and then they will reset and i can continue until the next time.

The wipers move at the correct speed while they are working and i have looked on VAGCOM but cannot find anything to do with wipers to look for a fault.

As always any help is always much appreciated.

Sound like the wiper linkage. You can take it apart or just get a new one from Skoda.

These are quite a common fault which usually is the linkage seized or the motor itself.

There is a thread on here somewhere with photos too of a strip and re fix of the linkage etc but i cannot find it at the moment.

Its not an electrical fault? If the linkage is seized how is it that turning the engine off and on resets them after a few attemps?

Sounds like the wiper motor com needs a good clean if you can get at it

well if the rain ever stops ill take it all apart and give it a good greasing up.

sounds like an electrical issue to me. The linkage fault will initially show as the wipers moving slowly and more juddery than normal till then eventually give up. Cycling the ingnition won't cure a mechanical fault like that. Could be the motor, wiring or switch. However I would maybe suggest that the motor is overheating and a thermal cutout is taking place?

Dodgy parking switch on the motor, a new motor usually cures it.

I have never really looked at the motor in detail (I had the linkage out to clean it all up 2 years ago). Is the parking switch an integral part of the motor and not replaceable seperately? Seems to be rather an expensive route in having to replace the whole motor for a faulty switch.

That was my thinking, the wipers work fine, no juddering, slowing down, squeeking etc they just stop and refuse to budge until i have removed power if you like.

Overheating the motor makes most sense to me. That suggests a part-seized linkage overloading the motor, despite the lack of judder.
