No high speed wiper
Al my wiper functions work fine except for high speed. If I push the lever to the top position the wipers stop wherever they happen to be.
Is it likely to just be the wiper switch?

Could be, could also be the relay! You could try swapping it with another similar relay and see if it helps!
I can't recall just now the exact relay but I think it's R2. You could swap it with the fog lamps relay which I think is R4 and see if it helps pin down the issue. yµ (idµ - eAµ) ψ=mψ

Only American cars have the fog relay I think.

Thanks for the help guys. I had a play with the relays, if I swap the slow and fast relays over the fault is still the same. If I take either of them out then no wiper function at all.
Is there anywhere where I can download wiring diagrams?

So it’s not the relay then.
Could be motor
You could try setting the switch to fast and then remove and insert the fast relay.
If it clicks on insertion the faults under the bonnet, and I would check for power at the motor next
I think that correct from memory

Pete, should have thought of that! Thanks for the prompt. Power at motor plug so it's time to get a replacement motor.
Thanks for your help.
