Wiper motor only working intermittently

No, not a thread about adding intermittent wipe.....but the 2-speed motor only working when it feels like it. :rolleyes:
As per the wiring diagram (50 is the motor, 51 the switch) there are 6 wires. With ignition on and the switch also, I'm getting 12+ volts at the coloured cable bullet connectors and there's good earth continuity to the motor case. I've checked the brushes and there's plenty of life left.
Any suggestions welcome!
Also, now it's on the bench, what should I need to connect up to a battery to test it? The two blue/greens to positive and the black to the earth terminal?
