Just wondering if this could be the motor or the switch or something else?

It doesnt always happen.

When i put the rear window wiper on it starts and stops about 1/3 of the way round. Put it on again it goes another 1/3 and if i keep doing it, it will eventually get back to where it started.

Anyone?

Does the switch have an intermitant setting or is it just on and off?, sounds like I stiff motor if it's a mk1-2 then getting one from a scrappy wouldn't hurt the bank and also rule that one out.

You could try turning the rear wiper on and going to the back and try helping it along the if it just the motor playing up

Its a mk3 mondeo

It has the intermitant settings but thats for the front wipers?

Helping it along doesnt help, you can hear the relay in the glove box clicking on and when it stops you can hear it clicking off

Then if i turn the wiper off and on again it moves like another bit round, then stops again, if i do this several times i can eventually get it back to where it sits

What controls where the wiper stops? Is it a micro switch in the motor or something?

Yes usually there is a circuit board to switch the motor off at the right piont, but the relay should only click off if you have turned the power off to it, try looking at the relay and the switch first tbh, the switch could just be dirty, you might be able to pull it apart and clean it up but it'll be fiddley, lastresort spray some contact cleaner in there but might wipe away the grease that's supposed to be in there.

Thanks, ill give that a go.

A motor from scrap yard is only Ł15 so might fire one in too just to rule that out. Then its either the relay or the switch if its still buggered

Hhmm! The more I think about it it pickles my brain lol, try the motor cos thinking about it it should have a constant feed to it so when you turn the power from the relay off to it it'll still return to it's closed position so in theory if the switch was being intermitant then you turn it on it'd wipe once then stop so yea try the motor first I would say is your best bet, and no probs my reply wasn't the clearest but we got there in the end
