Hi all is there a relay for the high beams, lows work fine. Thanks.

It's in the front fuse/ relay box under the hood/ bonnet. The larger of the two boxes. It's called the "DIP" replay: its #5. Have someone flick on the high beam and you should hear; or you can feel the relay clicking if you put your finger on it. You can try swapping one from another position to see if that fixes the problem....

Might also be a broken wire/solder connection in the multifunction switch.
