Can anyone tell me where to find the relay(s) for the wipers please. My intermittent wipe, flick wipe and self parking are all on the blink. Normal wiping on both speeds is fine. Anyone got any ideas?

Its the motor thats at fault. Thats a common failure symptom you've described there.

You can pull the motor apart and repair the motor bushes, but tbh, by the time you've got the motor out you might aswell just fit a new one. You can pick them up for ten a penny in the scrap yards becuase its a common part across a lot of different models in the Rover range, not just the 200.
