No dipped beam and no main beam but mains can be flashed. I have tried another switch and it was exactly the same. I have also changed the blue relay.

With the side lights switched on the sidelight bulbs light up and so do the dipped beam bulbs but the dipped beams are very dim. For some reason main beam then doesn't work and the blue light on the dash doesn't light up but if you flick the stalk the mains flash on and the blue light illuminates.
