Andrew you re a top man your advice worked a treat thankfullynin time for MOT
The mechanism was seriously rusted nothing was moving at all just lucky I did not cause more damage with trial and error
Blasted about half of the no jonsense screwfox pen oil can and everything started turning again and I got wipers great stuff thanks ever so much
Only issue is I lost the retaining clip yes I know but even though I really tried it got lost so I have temp cable around it but will need a more perm fix for that any advice wheee I could get one of those ?
