Front sidelights inop

Has anyone on here had a similar issue, having no sidelights on the front working, all other lights at the front workno bother, rear sidelights both work as should, all fuses are unbroken, have changed the bulbs, a few times both 501s and led bulbs with no joy, i also have no warning lights on the dash, have had it on the computer at my local garage, and no faults are shown, whats the chance someone could point me in the right direction before the motin september.

Thanks guys!
