Thanks for the response. When I stripped it down I saw the cam was on a collar and I was beginning to suspect it had moved.

Looking at the helpful article you referred to, it mentions centralising the cam. Should this be on the switch side or the opposite one?

Thanks again.

Glad to help .If you look at the exploded illustration and note no 17 , it refers to centralising trip . If that is the same as on your car , it goes central to the switch .Some older cars had a different , adjustable pin that was at the 12 o'clock position but the arm was a different setup .

Note no. 15 not 17 at bottom of illustation .
