Hi everyone
Thanks for the replies, I have tried it with the lights on, with the windscreen washers on, with both on, no response.
A friend has a look over the fuses and couldn't see anything unusual.
They are not something I would use but I will probably get an advisory in the NCT when it comes up. I feel it is probably an electrical issue as it does not appear to generate any noise or move even slightly.
Once again Thanks to those who replied
