Crazy Wipers

[Guest Chris Eccles]

I have read some of the early posts on wiper faults but none seem to quite describe

the symptoms on my Berlingo Van 2001 reg. What happens is this:

 

The wipers will always work at the #3 position of the switch (i.e: full speed)

 

They almost never work in either of the wash/wipe, #1 timed, or #2 half-speed settings.

 

When I have been driving for quite a while (30-45 mins), the wipers will

sometimes kick in to normal operation but usually only after I have been running

them at full speed for quite some time. (can only do this in moderate to heavy rain, obviously)

 

If I park and switch off the engine, the wipers usually don't work again immediately

upon restarting the vehicle.

 

Is this a symptom of these barmy multiplexed electrics ?

Why, oh why, could we not have just stuck with battery > switch > motor ? It seemed to

work fine for about 75 years of vehicle building !

Maybe the wiper switch needs changing or its internal contacts cleaning if it can be taken apart or switch cleaner squirted in. Could also be a loose connector.
