    You could follow the instructions for fittng the extra wire for cruise control for pre 2005 cars. There are a few things to do though it gives you direct access.

    Wiper arms off
    scuttle tray off
    wiper motor out
    the black plate behind wiper out, this leads into car above the cenral electronics module
    trim under steering column off

    Its not too hard a job if the arms come off ok, just leaving a bit off man handling to get the wiper motor out.

    Khufu, you are my new best friend!

    I did look at that route kinda, but one of my wiper arms is seized on.

    I have left some releasing spray soaking on it so it should come of when I have a go again.

    Is the a cruise guide on here anywhere do you know?

    I'd keep soaking arm & wiggling. Mine care off really easy!!! On a minus side, managed to crack a bit of the scuttle tray that clips down into below the windscreen (should have waited till warmer weather & plastic wasnt as brittle LOL) It cant actually be seen but as the trim isnt held now it sits up a bit. If you go down this route try to pry the trim edge at the windscreen upwards 1st before pulling towards front of the car. Will need to find time to sort mine LOL

    I never found an actual guide but more piecing bits on threads into a guide. Once you remove the black cover behind the wiper motor there is a plasic holder that holds several block connectors in place. Removing this (if you want) gives you enough space to stick you hand through LOL
