    Hi,

    Just seeing if anyone can help.. my car has all of a sudden started playing up.
    Rear wiper comes on when it wants and gets stuck in random positions.

    Numberplate light fault comes up on dash when they're both working fine.

    Windows won't do the convenience open when holding the unlock or lock button on the key fob.
    Offside rear door won't open sometimes if the car has been locked for long periods. And the alarm sometimes randomly goes off.
    This has literally all only started about a week ago.
    Anyone know of the issue be it battery or fuses?

    Any help greatly appreciated before I take to a garage ..

    Cheers

    Will

    Check to see if your rear wiper motor has leaked washer fluid inside the boot panel.

    Check the wiring on the offside front door shut.

    There was a leak last year just after I bought the car. It was on the boot lip when I opened the boot. I just figured it had run down the back of the car as it never happened again.

    The rear wiper motor is a pants design because the washer fluid pipe runs through the centre. When it leaks it kills the motor and other electrical bits in the boot door area (central locking, number plate lights etc.)

    Have a search on here both are common problems.

    Just had a search since you mentioned it and yeah seems a common fault.
    Is it a costly repair along with the replacement of the motor. Or a simple fix of the electrics with the replacement?

    Thanks for the replies up to now.

    Is this the correct Motor of you can see the attached picture. In the description is says it for my car but ebay says it isnt.
    Eurocarparts is £119 and I don't fancy paying that if I can get the same thing for £60
