Try the gearbox earth point, loosen it and twist it (if you have some wd40 or electrical contact spray give it the berries)re tighten. Check battery earth both ends of lead one being terminal. If none of this works it could be the comm 2000 unit top of steering column, all the stalks go into it including lights. Think a new one is £70 but you would need the correct one, there are several variants, use your vin number to get the right one if its faulty.

To add to that a faulty battery will play games too....

Yes good one elma, I would check earths, battery discharge check, if ok, alternator output.
Then think toward comm. A planet checkover may reveal cause.
