Dip and main beam not working

[area51]

As per the title.

Side lights, fog lights[front and rear] are all ok.

Head light flash on the column switch is also ok.

Car is W168 A class, any ideas??

Thanks

Have you checked the fuse's and bulbs?

Relay ?

Fuses and bulbs are all ok. I guess there must be a relay or two for the lights, I'll check this further,thanks.

I was wondering if it may be the switch itself ?

Update, the A class has no relays for exterior lights, it is all handled by the light switch.

I ended up fitting a new switch, which has got dip and main beam working again,but..

The parking lights [which worked ok when I bought the car] stopped working some time ago, I had hoped that the new switch would cure this as well but they still do not work.

As far as I can tell, if the side lights work then so should the parking lights. I have put a continuity meter across the new switch and have got continuity for sidelights/dip/front fog/rear fog. But no continuity across the switch for left or right parking lights.

Any ideas, please,as I would like to get my parking lights working again!

Thanks
