Windscreen wipers

[Wangler]

Does anyone know if my wipers are working as they should on my S3.

The top position of the stalk is off, the first one down gives what I guess is a normal speed of sweep, but it is intermittent, with about a two second delay between sweeps. The second one down gives a moderately fast speed. It makes no difference if the engine is running.

There is however no mention of an intermittent wiper function in the original owners handbook I have for the S3 and there is no sign of anything in the wiring diagram I have. The original owners handbook shows the “neutral” stalk position as being in the middle which is different to the way that mine works!

If I unplug the connection block close to the motor and wire the motor directly to a 12V power source using the Grey wire they run slow with no intermittency. With the Blue wire, the wipers go fast.
 
Are the wipers working as they should?

Up normally is standard (slow) middle is off Down is faster (slow!!)

Thanks Tim,

I had a feeling that mine wasn't standard. I can't see a module that would make them intermittent, but that doesn't mean there isn't one lurking there somewhere that was fitted many years ago.

I guess my anomaly must be a result of someone reconnecting the wires in a non-standard way. As I never deliberately take it out in the rain and the wipers function quite well - albeit not in the way that Lancia intended, I'll probably look for something else to tinker with instead!
