headlights not working correctly

[tookie2shoes]

Can anyone out there help?
My w reg Corsa headlights won't flash, although everything else works.
I've changed the stalk, but still no joy. Now maybe I need to check the relay, but I don't know where to look.

Any advice would be much appreciated

I think you should check your wiring & also there is a relay in the fuse box for the lamps.If the relay is tripping on there may be a short somewhere.After the relay cools off it will reset & your lamps will work again.
