I hope its of use to someone , here is a diagram of the wipers, fuses, switches etc in my TD5 defender. I had an issue of no high speed wipers and changed the steering column switch, the relay too. This is of use to use a m/meter to see if there is power to the motor from the switch etc to find damaged wired or bad fuses etc.
It show there is a powered resistor within the wiper motor itself which may be the culprit if you have slow and intermittent but no fast speed wipers like me.
A new Lucas motor is around £60.
