Can anyone tell me my problem,the only way i can get my wipers to work,is first go to fast wipe then come back to medium wipe, and intermitten wipe only works occassionally and if it does decides to work its about six intermitten wipes then stops,any any help would be appreciated.

Cheers :thumbsup:

Hej,

My Mk1 2000 Berlingo started to do exactly the same problem as described by the initiator of the topic.
Could not find an answer from topic, was the certain fault found/resolved.
Will start to figure out mine, keep posted.

I would probably say that the motor brushes are wearing out. If it is this you will find that after a while switching it to full speed first won't work either.

I had very similar problems. There were loads of causes suggested but I simply went to the breaker's yard and found another motor (for £10) and replaced the problematic one. This has now been fine for about 5 years!

I recently had this problem. It turned out to be bad / dirty connection between brushes and commutator in the motor. Took rotor out cleaned surfaces and and works ok. I had to bend tabs back which hold brushes in to get rotor back into place I guess they would snap off if you did this more than once

Thx for the info.
For my own interest, I did remove the wiper-motor and checked the condition:

The brushes are quite worn out, but unfortunately they are not meant to be replaceable ... although it is possible if extremely interested and skilled.
But I just tensioned the brush's springs and cleaned the contact surface on rotor.

Aftermarket new motor costs approx 23€ ... so not that biggy if needed. So far the cleaning helped.
Also, as everything was already on the table, cleaned and renewed the lubricant on all moving parts/shafts + new O-rings on shaft ends:

   

   

   

   

   

So far wipers work again nicely on low speed.

A good bit of 'proper' mending!   If in desperation you need new brushes go to a washing machine service centre - they'll have lots of different sorts and its very easy to sand down the brush to fit the holder.
