Hi Nick and Hi to you all.
I have just put a new wiper switch on the car and it's still not working.
Moto is ok tested
switch is ok new
fuse is ok tested
I have swopped the relays over
I am only geting volts on one wire to the moto with the ignition off and with the ignition on and with the switch on slow or fast
now at a loss


all the best
peter

I had a similar problem on my Defender. Turned out to be a dodgy connection at the rear of the fuse box.
Try tracing the wiring through and checking each connection in the circuit.
