Dave,
Yes I have the right one, the large one in the bank of 5.
The strange thing is that the intermittent and slow and fast speed positions have the same problem occasionally.
When the wipers wont stop by turning off at the switch if I pull the relay out of it's base and then re-insert it the wipers stop!
It certainly points to a relay problem but I'm now on the 3rd relay and still have the fault.
The replacement relays are the correct type like the one fitted when the car was delivered from Morgan.
Thanks for the reply and suggestion.
